PuffinFileAccessor is for opening readers and writers for puffin files.

Required Associated Types

type Reader: SizeAwareRangeReader + Sync

type Writer: AsyncWrite + Unpin + Send

type FileHandle: ToString + Clone + Send + Sync

Required Methods

fn reader<'life0, 'life1, 'async_trait>( &'life0 self, handle: &'life1 Self::FileHandle, ) -> Pin<Box<dyn Future<Output = Result<Self::Reader>> + Send + 'async_trait>>

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

Opens a reader for the given puffin file handle.

fn writer<'life0, 'life1, 'async_trait>( &'life0 self, handle: &'life1 Self::FileHandle, ) -> Pin<Box<dyn Future<Output = Result<Self::Writer>> + Send + 'async_trait>>

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

Creates a writer for the given puffin file handle.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
