Trait Implementations

impl Clone for RamDirectory

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RamDirectory

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

Formats the value using the given formatter.

impl Default for RamDirectory

fn default() -> RamDirectory

Returns the “default value” for a type.

impl Directory for RamDirectory

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

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

Check if a file exists

fn file_size<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path, ) -> Pin<Box<dyn Future<Output = Result<u64>> + Send + 'async_trait>>

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

Get file size

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

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

Open a file for reading, returns a FileSlice (loads entire file)

fn read_range<'life0, 'life1, 'async_trait>( &'life0 self, path: &'life1 Path, range: Range<u64>, ) -> Pin<Box<dyn Future<Output = Result<OwnedBytes>> + Send + 'async_trait>>

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

Read a specific byte range from a file (optimized for network)

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

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

List files in directory

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

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

Open a lazy file handle that fetches ranges on demand This is more efficient for large files over network

impl DirectoryWriter for RamDirectory

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

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

Create/overwrite a file with data

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

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

Delete a file

fn rename<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, from: &'life1 Path, to: &'life2 Path, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

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

Atomic rename

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

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

Sync all pending writes
