Struct CancelRequest

#[non_exhaustive]
pub struct CancelRequest {
    pub pid: i32,
    pub secret_key: SecretKey,
}

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

pid: i32

secret_key: SecretKey

Implementations

impl CancelRequest

pub fn new(pid: i32, secret_key: SecretKey) -> Self

Constructs a new CancelRequest.

impl CancelRequest

pub fn is_cancel_request_packet(buf: &[u8]) -> bool

try to inspect the buf if it’s a cancel request packet

Trait Implementations

impl Debug for CancelRequest

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

Formats the value using the given formatter.

impl Message for CancelRequest

fn decode(buf: &mut BytesMut, ctx: &DecodeContext) -> PgWireResult<Option<Self>>

Please call is_cancel_request_packet before calling this if you don’t want to get an error for non-CancelRequest packet.

fn message_length(&self) -> usize

Return the length of the message, including the length integer itself.

fn max_message_length() -> usize

Return the max length of message in this type.

fn encode_body(&self, buf: &mut BytesMut) -> PgWireResult<()>

Encode body part of the message.

fn decode_body( buf: &mut BytesMut, msg_len: usize, ctx: &DecodeContext, ) -> PgWireResult<Self>

Decode body part of the message.

fn message_type() -> Option<u8>

Return the type code of the message. In order to maintain backward compatibility, Startup has no message type.

fn encode(&self, buf: &mut BytesMut) -> PgWireResult<()>

Default implementation for encoding message.

impl PartialEq for CancelRequest

fn eq(&self, other: &CancelRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
