Struct LocalStorage 

pub struct LocalStorage { /* private fields */ }

Filesystem-backed binary cache storage.

Implementations

impl LocalStorage

pub fn new(path: impl Into<PathBuf>) -> Self

Create a new local storage backend rooted at path.

The directory structure is created lazily on first write.

pub fn root(&self) -> &Path

Return the root path.

Trait Implementations

impl Clone for LocalStorage

fn clone(&self) -> LocalStorage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LocalStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Delete a store path’s narinfo and associated NAR blob.

fn list_narinfos<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, CacheError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
