Trait representing a way to get pieces

Required Methods

fn get_piece<'life0, 'async_trait>( &'life0 self, piece_index: PieceIndex, ) -> Pin<Box<dyn Future<Output = Result<Option<Piece>>> + Send + 'async_trait>>

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

Get piece by index

fn get_pieces<'a, 'async_trait, PieceIndices>( &'a self, piece_indices: PieceIndices, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn Stream<Item = (PieceIndex, Result<Option<Piece>>)> + Send + Unpin + 'a>>> + Send + 'async_trait>>

where PieceIndices: IntoIterator<Item = PieceIndex, IntoIter: Send> + Send + 'a + 'async_trait, Self: 'async_trait, 'a: 'async_trait,

Get pieces with provided indices.

Number of elements in returned stream is the same as number of unique piece_indices.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
