Struct CacheRuntime 

pub struct CacheRuntime { /* private fields */ }

Ties policy resolution + content-addressed key derivation + single-flight compute-through into one call the dispatch path makes per tool. The enterprise injects a Redis backend + the real tenant; the OSS default is an in-process backend under a "local" tenant. This is the whole runtime contract for §85 — a hit returns before compute runs (so a budget gate placed after the lookup never sees it, D85.3).

Implementations

impl CacheRuntime

pub fn new(backend: Arc<dyn CacheBackend>, tenant: impl Into<String>) -> Self

pub fn in_process() -> Self

In-process, single-tenant default (OSS runtime with no injected tier).

pub fn dispatch<F, E>( &self, ir: &IRProgram, tool: &IRToolSpec, args: &[(String, String)], compute: F, ) -> Result<CacheOutcome, E>

where F: FnOnce() -> Result<Vec<u8>, E>,

Look up (or compute-and-store) a tool result. args is the full bound (name, value) set; the key: subset (if any) is applied here. compute runs ONLY on a miss and its error is never cached (D85.10).

pub fn invalidate(&self, cache_name: &str)

Flush a cache namespace (called when an emit fires on one of its invalidate_on: channels).
