Struct Describe

#[non_exhaustive]
pub struct Describe {
    pub target_type: u8,
    pub name: Option<String>,
}

Describe command fron frontend to backend. For getting information of particular portal or statement

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.

target_type: u8

name: Option<String>

Implementations

impl Describe

pub fn new(target_type: u8, name: Option<String>) -> Self

Constructs a new Describe.

Trait Implementations

impl Debug for Describe

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

Formats the value using the given formatter.

impl Message for Describe

fn message_type() -> Option<u8>

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

fn message_length(&self) -> usize

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

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

Encode body part of the message.

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

Decode body part of the message.

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

Default implementation for encoding message.

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

Default implementation for decoding message.

impl PartialEq for Describe

fn eq(&self, other: &Describe) -> 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.
