Struct DataRow

#[non_exhaustive]
pub struct DataRow {
    pub data: BytesMut,
    pub field_count: i16,
}

Data structure for postgresql wire protocol DataRow message.

Data can be represented as text or binary format as specified by format codes from previous RowDescription 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.

data: BytesMut

field_count: i16

Implementations

impl DataRow

pub fn new(data: BytesMut, field_count: i16) -> Self

Constructs a new DataRow.

Trait Implementations

impl Clone for DataRow

fn clone(&self) -> DataRow

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataRow

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

Formats the value using the given formatter.

impl Default for DataRow

fn default() -> DataRow

Returns the “default value” for a type.

impl Message for DataRow

fn message_type() -> Option<u8>

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

fn max_message_length() -> usize

Return the max length of message in this 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, msg_len: usize, _ctx: &DecodeContext, ) -> 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, ctx: &DecodeContext) -> PgWireResult<Option<Self>>

Default implementation for decoding message.

impl PartialEq for DataRow

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

impl Eq for DataRow
