ModelsDiskCache

mold_server::state

Struct ModelsDiskCache 

Source 
pub struct ModelsDiskCache { /* private fields */ }
Expand description

Last-good disk stats for the models dir plus a single-flight refresh claim. /api/status reads the snapshot synchronously and — when it has gone stale — at most one request wins the claim and kicks a background spawn_blocking refresh; everyone else keeps serving the last-good value. A hung statvfs therefore costs one leaked blocking-pool thread and a stale stat, never a parked runtime worker.

Implementations§

Source§

impl ModelsDiskCache

Source

pub fn read(&self) -> (Option<DiskUsage>, bool)

Current snapshot plus whether the caller won the refresh claim. Returns true at most once per stale period — the winner must call ModelsDiskCache::store (or ModelsDiskCache::release) to let the next refresh happen.

Source

pub fn store(&self, usage: Option<DiskUsage>)

Publish a fresh snapshot and release the refresh claim.

Source

pub fn release(&self)

Release the refresh claim without publishing (refresh task failed).
