Struct Label 

pub struct Label(/* private fields */);

A grammar-checked string property.

Construction is only possible through Label::sanitize. The grammar admits catalog and repository identifiers (Qwen2.5-7B-Instruct-Q4_K_M, Qwen/Qwen2.5-7B) and rejects anything path-shaped, whitespace-bearing, or over-long.

use mesh_llm_analytics::Label;

assert!(Label::sanitize("Qwen/Qwen2.5-7B").is_some());
assert!(Label::sanitize("/Users/dan/models/private.gguf").is_none());

Implementations

impl Label

pub fn sanitize(value: &str) -> Option<Self>

Accept value only if it matches the label grammar.

The grammar is: ASCII alphanumerics plus ., -, _, +, and at most one interior /; no leading or trailing separator; no ..; at most [MAX_LABEL_LEN] characters.

+ is admitted for semver build metadata (0.76.0+gABCDEF.dirty), which is the version string this crate reports about itself.

pub fn slug(value: &str) -> Option<Self>

Normalize a human-readable device name into a label.

Hardware probes return names like Apple M4 Max or NVIDIA GeForce RTX 4090, which Label::sanitize rejects for containing spaces.

Collapsing separators is dangerous on its own: it would turn /home/dan/my model.gguf into the perfectly valid-looking home-dan-my-model.gguf, laundering a path past the grammar. Two extra rules prevent that, and they are why this is a distinct constructor rather than a pre-pass on sanitize:

• Input containing a path separator is refused outright, never normalized.
• The result is capped at [MAX_SLUG_SEGMENTS] segments and [MAX_SLUG_LEN] characters, which every real device name fits and prose does not.

use mesh_llm_analytics::Label;

assert_eq!(Label::slug("Apple M4 Max").unwrap().as_str(), "apple-m4-max");
assert!(Label::slug("/Users/dan/models/private.gguf").is_none());

pub fn redacted() -> Self

A label for a value that failed sanitization, so counts stay complete.

pub fn sanitize_or_redact(value: &str) -> Self

Sanitize value, falling back to Label::redacted.

Use this when the count matters more than the identity, so an unrecognized model name still contributes to totals without leaking whatever the user actually typed.

pub fn slug_or_redact(value: &str) -> Self

Slug value, falling back to Label::redacted.

pub fn as_str(&self) -> &str
