pub struct Cache { /* private fields */ }Expand description
The main cache abstraction.
While the cache is active, it holds a read (shared) lock that prevents cache cleaning
Implementations§
Source§impl Cache
impl Cache
Sourcepub fn with_refresh(self, refresh: Refresh) -> Self

Sourcepub fn must_revalidate_package(&self, package: &PackageName) -> bool
pub fn must_revalidate_package(&self, package: &PackageName) -> bool
Returns true if a cache entry must be revalidated given the Refresh policy.
Sourcepub fn must_revalidate_path(&self, path: &Path) -> bool
pub fn must_revalidate_path(&self, path: &Path) -> bool
Returns true if a cache entry must be revalidated given the Refresh policy.
Sourcepub fn freshness(

Persist a temporary directory to the artifact store, returning its unique ID.
Sourcepub fn is_temporary(&self) -> bool
pub fn is_temporary(&self) -> bool
Returns true if the Cache is temporary.
Sourcepub fn clear(self, reporter: Box<dyn CleanReporter>) -> Result<Removal, Error>
pub fn clear(self, reporter: Box<dyn CleanReporter>) -> Result<Removal, Error>
