Struct Packet 

pub struct Packet {
    pub header: PacketHeader,
    pub payload: BytesMut,
}

A TDS packet with header and payload.

Fields

header: PacketHeader

Packet header.

payload: BytesMut

Packet payload (excluding header).

Implementations

impl Packet

pub fn new(header: PacketHeader, payload: BytesMut) -> Self

Create a new packet with the given header and payload.

pub fn total_size(&self) -> usize

Get the total packet size including header.

pub fn is_end_of_message(&self) -> bool

Check if this is the last packet in a message.

Trait Implementations

impl Clone for Packet

fn clone(&self) -> Packet

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Packet

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Encoder<Packet> for TdsCodec

type Error = CodecError

The type of encoding errors.

fn encode( &mut self, item: Packet, dst: &mut BytesMut, ) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.

impl<T> Sink<Packet> for PacketStream<T>

where T: AsyncWrite + Unpin,

type Error = CodecError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Packet) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.

impl<T> Sink<Packet> for PacketWriter<T>

where T: AsyncWrite + Unpin,

type Error = CodecError

The type of value produced by the sink when an error occurs.

fn poll_ready( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Packet) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

Flush any remaining output and close this sink, if necessary.
