Struct LocalStorage 

pub struct LocalStorage { /* private fields */ }

Filesystem-backed binary cache storage.

Implementations

impl LocalStorage

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

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<(), Error>

Formats the value using the given formatter.

impl StorageBackend for LocalStorage

fn wipe_all<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize, StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, LocalStorage: 'async_trait,

Complete L3 wipe: remove the entire cache directory (narinfos + the nar/ blob subtree), reclaiming NAR bytes a per-hash delete cannot reach. The directory is re-created lazily on the next put. Returns the narinfo count removed.

fn get_narinfo<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<String>, StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, LocalStorage: 'async_trait,

Retrieve narinfo text by store path hash.

fn put_narinfo<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, hash: &'life1 str, content: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, LocalStorage: 'async_trait,

Store narinfo text keyed by store path hash.

fn get_nar<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<Vec<u8>>, StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, LocalStorage: 'async_trait,

Retrieve a NAR blob by its relative path.

fn put_nar<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, path: &'life1 str, data: &'life2 [u8], ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, LocalStorage: 'async_trait,

Store a NAR blob at the given relative path.

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, hash: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, LocalStorage: '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>, StoreError>> + Send + 'async_trait>>

where 'life0: 'async_trait, LocalStorage: 'async_trait,

List all stored narinfo hashes.
