Enum mysql_common::proto::codec::ChunkDecoder
source · pub enum ChunkDecoder {
Idle,
Chunk {
seq_id: u8,
needed: NonZeroUsize,
},
}
Expand description
Decoder for MySql protocol chunk.
Variants§
Idle
Decoder is waiting for the first or subsequent packet chunk.
It’ll need at least 4 bytes to start decoding a chunk.
Chunk
Chunk is being decoded.
Fields
§
needed: NonZeroUsize
Number of bytes needed to finish this chunk.
Implementations§
source§impl ChunkDecoder
impl ChunkDecoder
sourcepub fn decode<T>(
&mut self,
src: &mut BytesMut,
dst: &mut T,
max_allowed_packet: usize,
) -> Result<Option<ChunkInfo>, PacketCodecError>
pub fn decode<T>( &mut self, src: &mut BytesMut, dst: &mut T, max_allowed_packet: usize, ) -> Result<Option<ChunkInfo>, PacketCodecError>
Will try to decode MySql packet chunk from src
to dst
.
If chunk is decoded, then ChunkInfo
is returned.
If the dst
buffer isn’t empty then it is expected that it contains previous chunks
of the same packet, or this function may erroneously report
PacketCodecError::PacketTooLarge
error.
