Struct CacheState

Source

struct CacheState {
    cache_lock: RecursiveLock,
    mutate_lock: RecursiveLock,
}

Expand description

The state of the CacheLocker.

Fields§

§cache_lock: RecursiveLock

The cache lock guards the package cache used for download and resolution (append operations that should not interfere with reading from existing src files).

§mutate_lock: RecursiveLock

The mutate lock is used to either guard the entire package cache for destructive modifications (in exclusive mode), or for reading the package cache src files (in shared mode).

Note that CacheLockMode::MutateExclusive holds both CacheState::mutate_lock and CacheState::cache_lock.
