Trait Implementations

impl UploadSink for FsSink

fn write<'life0, 'life1, 'async_trait>( &'life0 mut self, buf: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>

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

Append buf at the sink’s current position.

fn write_at<'life0, 'life1, 'async_trait>( &'life0 mut self, offset: u64, buf: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>

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

Write buf at an absolute offset within the destination.

fn received_ranges<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Vec<ChunkRange>, StorageError>> + Send + 'async_trait>>

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

The contiguous byte ranges of the destination already received.

fn len<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64, StorageError>> + Send + 'async_trait>>

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

Current length of the destination, for size validation before commit.

fn commit<'async_trait>( self: Box<Self>, ) -> Pin<Box<dyn Future<Output = Result<FileMeta, StorageError>> + Send + 'async_trait>>

where Self: 'async_trait,

Finish the stream, finalize the destination and return its metadata.

fn abort<'async_trait>( self: Box<Self>, ) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>

where Self: 'async_trait,

Discard the temporary data and clean up.
