Keep the thread-record documentation contract-focused.
Lines 44-46 enumerate platform APIs and repeat implementation types (I32, U64, and U32). State the exposed contract instead: native_id stores a valid, non-negative operating-system thread identifier as U64. Keep platform-specific API rationale outside this public doc comment.
As per path instructions, docstrings must state the contract, not the mechanism, and must not restate types.

quent_yaml parse_from_str Rust YAML escape \x double quoted scalar
💡 Result:
In the context of the quent-yaml crate (part of the Quent project), the parse_from_str function is used to deserialize YAML strings into a schema model [1][2]. The internal implementation relies on serde-saphyr to process the YAML structure [1][2]. Regarding YAML double-quoted scalars and escape sequences, YAML 1.2 specifications—which standard Rust YAML parsers like yaml-rust2 and others typically adhere to—support specific escape sequences within double-quoted strings [3]. For hex-encoded characters, the specification supports the \xHH escape sequence, where HH is a two-digit hexadecimal number [4][5]. When using a Rust YAML parser, ensure your deserialization logic or underlying YAML engine (such as serde-saphyr in the case of quent-yaml) correctly handles the YAML 1.2 escape rules [1][3][6]. If you are encountering issues where \x escape sequences are not being interpreted as expected, verify the following: 1. Double-quote consistency: Ensure the scalar is properly enclosed in double quotes ("..."), as single-quoted scalars in YAML do not support most escape sequences [6]. 2. Parser compliance: If the library does not support \xHH, it may be due to incomplete YAML 1.2 support, in which case you might need to use a more strictly compliant library or process the string manually after parsing [3]. 3. Manual handling: If you are implementing a custom parser or need to handle these escapes post-parse, you can replace the \xHH sequences by iterating through the string and parsing the two hexadecimal characters following the \x marker into their corresponding character values [7][4][5].

serde-saphyr YAML 1.2 double quoted scalar \\x escape support parse_from_str version
💡 Result:
The serde-saphyr YAML library does not explicitly document or showcase support for \x hex escape sequences (e.g., \xHH) in its processing of double-quoted YAML scalars [1]. Official documentation and existing test suites for serde-saphyr confirm that double-quoted strings support standard escape sequences like \n, \t, \r, \, ", and unicode escapes such as \uXXXX [1]. However, tests for double-quoted string processing focus on common control characters and do not demonstrate the use of \x hex escapes [1]. Because the library emphasizes compliance with YAML standards, support for \x might be limited or absent depending on the specific underlying parser implementation, which deviates from YAML 1.2 specifications that primarily rely on \u and \U for hex/unicode escapes in double-quoted scalars. If you require specific escape handling, you should verify behavior through a local test case using serde_saphyr::from_str, similar to the established testing patterns found in the crate's source code [1]. Options for YAML 1.2 compliance (such as toggling yaml_12 in SerializerOptions) affect boolean and scalar heuristic behaviors rather than the specific syntax of double-quoted escape sequences [2][3].

serde-saphyr 1.1.0 source granit-parser escape \x YAML
💡 Result:
In the context of the serde-saphyr 1.1.0 crate and its underlying dependency, granit-parser, here is how character escapes (such as \x) are handled in YAML: 1. Escape Processing: The granit-parser is responsible for parsing YAML and performs escape processing for scalars, specifically within double-quoted strings. This includes standard Unicode escapes like \uXXXX [1]. 2. Hexadecimal Escapes (\x): While YAML specifications primarily define \uXXXX (4-digit hex) and \UXXXXXXXX (8-digit hex) for Unicode escapes, standard YAML parsers typically do not support \xXX (2-digit hex) escapes by default as part of the formal YAML specification. If you are encountering issues with \x sequences, it is because they are not valid escape sequences in standard YAML, and the underlying parser (granit-parser) follows these rules. 3. Serialization Behavior: In serde-saphyr, when configuring serialization via SerializerOptions, the library handles escape sequences for control characters (such as \n, \t, \r, and backslashes) by automatically switching from single-quoted strings to double-quoted strings when these sequences are present [2]. 4. Parser Implementation: Granit-parser is a low-level event parser that emits a stream of YAML events [3][4]. Its scalar processing logic handles these escapes as part of its compliance with YAML's rules for double-quoted scalars [5][1]. If an escape sequence is not recognized (like an invalid or non-standard \x), it will typically be treated as a literal character or rejected depending on the scanner's strictness [1]. If you need to represent specific bytes or characters that \x would normally handle, you should use the standard YAML Unicode escape sequences (\uXXXX) if the character is representable in Unicode, or ensure the data is encoded/handled within your Rust types before serialization [2][1].

official YAML 1.2 specification double quoted escape sequences \\xXX
💡 Result:
In the official YAML 1.2 specification (including versions 1.2 and 1.2.2), the \xXX escape sequence is officially supported within double-quoted scalars [1][2]. This escape sequence is classified as an 8-bit escape sequence [3][4] and is used for encoding non-printable or 8-bit (ISO 8859-1) characters [1][5]. YAML 1.2 adopts familiar C-style escape sequences for double-quoted strings [1][6]. Beyond 8-bit characters, the specification also supports 16-bit (\uXXXX) and 32-bit (\UXXXXXXXX) Unicode escape sequences to represent broader character sets [1][5]. Key points regarding escape sequences in YAML 1.2: * Interpretation: Escape sequences are interpreted only within double-quoted scalars [2]. In other scalar styles (such as single-quoted or plain), the backslash (\) character has no special meaning and does not trigger escape sequence interpretation [2]. * Purpose: Escape sequences are primarily intended to present characters that might otherwise be non-printable or to encode specific byte values [1][5]. * Implementation: Each escape sequence must be parsed into the appropriate Unicode character; the original sequence is considered a presentation detail and should not be used to convey content information [2].

site:docs.rs/granit-parser "xXX" escape
💡 Result:
There is no standard technical definition or universal "xXX" escape sequence in programming, terminals, or general computing. Based on the provided search results, the term "xXX" does not appear as a recognized escape sequence, control character, or functional command in the context of the analyzed technical documentation (which pertains to a Rust-based YAML parser). In technical contexts, "xXX" is commonly used as a placeholder or template where: 1. "x" represents a prefix or literal character (such as the 'x' in hexadecimal escape sequences like \xXX). 2. "XX" represents variable data or a placeholder for two hex digits. If you encountered "xXX" in a specific codebase or configuration file, it is likely a placeholder intended to be replaced with actual values, such as a specific hexadecimal character code.

Preserve separators decoded from YAML escapes.
collision_free_namespace_separator checks raw YAML before serde_saphyr::from_str decodes escapes. A scalar such as "\u0051uentNamespaceSeparator" can therefore decode to QuentNamespaceSeparator without triggering suffixing. restore_namespaces then replaces that literal value with :: in every Value::String. Add a regression test and keep literal scalar content distinct from namespace markers.

collision_free_namespace_separator and restore_namespaces so separator collision
detection uses decoded YAML scalar content, while literal scalar values remain
distinguishable from generated namespace markers and are not replaced
indiscriminately. Add a regression test covering an escaped YAML separator such
as \u0051uentNamespaceSeparator and verify the decoded literal is preserved.

I'm working on some more mods in parallel, e.g. #686 #683, but I realized the YAML syntax used there is a bit more consistent w.r.t. what I'm proposing here, which feels kind of weird compared to the other mods. I think it's best to consolidate on <whatever scope>:
<mod name>:
<scope-specific mod key>: <value>So here I'm thinking about moving to: entities:
Foo:
events:
bar:
attributes:
my_field_name_for_pid: { os: process }
my_field_name_for_tid: { os: thread }
Which would make it consistent with the other approaches |
