Struct FsStorage 

pub struct FsStorage { /* private fields */ }

Available on crate feature storage-fs only.

A filesystem-backed object store rooted at a base directory.

Keys are treated as relative paths under root; parent directories are created on put. put_file is overridden to rename when the source and destination share a filesystem, avoiding the read-into-memory round-trip.

Implementations

impl FsStorage

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

Create a backend rooted at root. The directory is created lazily.

Trait Implementations

impl Clone for FsStorage

fn clone(&self) -> FsStorage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FsStorage

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

Formats the value using the given formatter.

impl StorageBackend for FsStorage

fn put<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 str, data: Bytes, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Write data at key. Overwrites if the key exists.

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

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

Read the object stored at key.

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

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

Delete the object at key.

fn list<'life0, 'life1, 'async_trait>( &'life0 self, prefix: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>>> + Send + 'async_trait>>

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

List all keys with the given prefix.

fn put_file<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, key: &'life1 str, path: &'life2 Path, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Write the file at path to key, then remove the source file.

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

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

Returns true if the object exists.
