Struct CacheSnapshotStore 

pub struct CacheSnapshotStore { /* private fields */ }

Session-scoped previous-component snapshot (see module docs). Shared via Arc inside TraceContext; all mutation is under one internal mutex so compare-and-update is atomic per emitted request.

Implementations

impl CacheSnapshotStore

pub fn new() -> Self

pub fn compare_and_update( &self, key: Option<&TraceDigestKey>, tools_schema: &[Value], system_prompt: Option<&str>, messages: &[SharedMessage], ) -> CacheDiagnostics

Compare the current request’s components against the previous snapshot, update the snapshot, and return the diagnostics. Requires the digest key — without it no digests exist to compare, so the caller gets CacheDiagnostics::default() and the snapshot is left untouched (never cleared: a transient key failure must not turn the next successful comparison into a spurious New).

pub fn last_activity(&self) -> Option<CacheActivity>

Latest computed cache activity (for /context).
