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.

Returns Ok(None) if the piece is not found. Returns Err(_) if trying to get the piece caused an error.

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

where Self: 'async_trait, 'a: 'async_trait,

Get pieces with provided indices.

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

Dyn Compatibility

This trait is dyn compatible.

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