Struct GraphCache 

pub struct GraphCache { /* private fields */ }

A caller-owned cache of graphs built from complete resolution claims.

The cache is mutated through &mut self, so a host chooses its own synchronization policy for construction. Every handle it returns may outlive it and may be shared across threads.

Implementations

impl GraphCache

pub fn new(limits: GraphCacheLimits) -> Self

An empty cache bounded by one host-chosen retention budget.

pub fn build_rust_graph( &mut self, snapshot: &RustResolutionSnapshot, resolution: &RustTargetResolution, limits: GraphLimits, ) -> Result<CachedCodeGraph, GraphBuildError>

Project one snapshot-bound Rust resolution, reusing an exact earlier answer when the caller states exactly the same claim.

The returned graph is the one crate::build_rust_graph_with_limits returns for the same arguments, whatever this cache retained first.

Errors

The same refusals as the direct builders. Both identity refusals are taken before any retained state is examined, so a mismatched pairing cannot be answered from, or recorded against, this cache.

pub fn stats(&self) -> GraphCacheStats

What this cache has done so far.

pub fn clear(&mut self)

Drop every retained graph and every retained source projection.

Cumulative statistics are not reset, and no handle a caller holds is invalidated: the cache drops its own strong references and nothing else.
