Trait Decoder

pub unsafe trait Decoder: InternalHandleDecoder {
    // Required methods
    fn take_chunks_raw(
        &mut self,
        count: usize,
    ) -> Result<NonNull<Chunk>, DecodeError>;
    fn finish(&mut self) -> Result<(), DecodeError>;
}

A decoder for FIDL messages.

Safety

Pointers returned from take_chunks must:

• Point to count initialized Chunks
• Be valid for reads and writes
• Remain valid until the decoder is dropped

The decoder may be moved without invalidating the returned pointers.

Required Methods

fn take_chunks_raw( &mut self, count: usize, ) -> Result<NonNull<Chunk>, DecodeError>

Takes a slice of Chunks from the decoder, returning a pointer to them.

Returns Err if the decoder doesn’t have enough chunks left.

fn finish(&mut self) -> Result<(), DecodeError>

Finishes decoding.

Returns Err if the decoder did not finish successfully.
