Struct IdentificationCache 

pub struct IdentificationCache { /* private fields */ }

A freshness-keyed cache of identification results, safe to share across threads. A cache miss (or any lock failure) falls back to a direct identify, so the cache is only ever an optimization. A changed top-level mtime or size (an added/removed/replaced immediate child, or a rewritten file) invalidates the entry; see the module docs for the depth-1 limitation.

Implementations

impl IdentificationCache

pub fn new() -> Self

An empty cache.

pub fn hit_count(&self) -> usize

The number of cache hits so far (for diagnostics/tests).

pub fn identify(&self, record: &ModelRecord) -> IdentifiedModel

Identify record, returning a cached result when the model’s bytes are unchanged since the last identification.

Trait Implementations

impl Default for IdentificationCache

fn default() -> IdentificationCache

Returns the “default value” for a type.
