Struct Startup 

#[non_exhaustive]
pub struct Startup {
    pub protocol_number_major: u16,
    pub protocol_number_minor: u16,
    pub parameters: BTreeMap<String, String>,
}

Postgresql wire protocol startup message.

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.

protocol_number_major: u16

protocol_number_minor: u16

parameters: BTreeMap<String, String>

Implementations

impl Startup

pub fn new() -> Self

Constructs a new Startup.

impl Startup

Protocol version 3.0

pub const PROTOCOL_VERSION_3_2: i32 = 196610

Protocol version 3.2

pub const PG_PROTOCOL_EARLIEST: u16 = 3

Earliest supported major protocol version

pub const PG_PROTOCOL_LATEST: u16 = 3

Latest supported major protocol version

Trait Implementations

impl Debug for Startup

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

Formats the value using the given formatter.

impl Default for Startup

fn default() -> Startup

Returns the “default value” for a type.

impl Eq for Startup

impl Message for Startup

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

Default implementation for decoding 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.
