Struct PacketCodec

Source
pub struct PacketCodec {
    pub max_allowed_packet: usize,
    /* private fields */
}
Expand description

Codec for MySql protocol packets.

Codec supports both plain and compressed protocols.

Fields§

§max_allowed_packet: usize

Maximum size of a packet for this codec.

Implementations§

Source§

impl PacketCodec

Source

pub fn reset_seq_id(&mut self)

Sets sequence id to 0.

Source

pub fn sync_seq_id(&mut self)

Overwrites plain sequence id with compressed sequence id.

Source

pub fn compress(&mut self, level: Compression)

Turns compression on.

Source

pub fn decode<T>( &mut self, src: &mut BytesMut, dst: &mut T, ) -> Result<bool, PacketCodecError>
where T: AsRef<[u8]> + BufMut,

Will try to decode a packet from src into dst.

Returns

  • true - decoded packet was written into the dst,
  • false - src did not contain a full packet.
Source

pub fn encode<T: Buf>( &mut self, src: &mut T, dst: &mut BytesMut, ) -> Result<(), PacketCodecError>

Will encode packets into dst.
