Struct CachePolicyTable 

pub struct CachePolicyTable { /* private fields */ }

Per-route cache headers derived from the built manifest. Empty = no route declared a non-inert policy, and every apply is a no-op.

Implementations

impl CachePolicyTable

pub fn from_routes(routes: &[Route]) -> Self

Build from the manifest’s routes. Routes whose policy is inert ({ ttl: 0 } — the “never cache this” every route file writes) produce no rule, so the table stays empty for the common workload and this layer costs one is_empty per response.

pub fn from_manifest_json(raw: &[u8]) -> Result<Self>

Build from a built manifest.json’s bytes.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn cache_control_for(&self, path: &str) -> Option<&str>

The Cache-Control a 2xx at path must carry, or None when no route declared a positive policy for it.

The header-free accessor exists for the publish path, which stamps a value onto an object at PUT time rather than onto a live response and has no axum dependency of its own. Same rules, same first-match-wins order — a second derivation over there is precisely the drift this module was pulled down into mesofact-core to prevent.

pub fn apply(&self, path: &str, status: StatusCode, headers: &mut HeaderMap)

Stamp the first matching route’s derived headers onto headers.

First match wins, matching the manifest’s own routing rule — the same discipline mesofact::route_headers states for the domain table.
