Implementations

impl TvpWireType

pub const fn type_id(&self) -> u8

Get the TDS type ID.

pub fn encode_type_info(&self, buf: &mut BytesMut)

Encode the TYPE_INFO for this column type.

Trait Implementations

impl Clone for TvpWireType

fn clone(&self) -> TvpWireType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TvpWireType

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

Formats the value using the given formatter.

impl PartialEq for TvpWireType

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