Implementations

impl TvpColumnType

pub fn from_sql_type(sql_type: &str) -> Option<Self>

Infer the TVP column type from an SQL type name string.

This parses SQL type declarations like “INT”, “NVARCHAR(100)”, “DECIMAL(18,2)”.

pub const fn type_id(&self) -> u8

Get the TDS type ID for this column type.

pub const fn max_length(&self) -> Option<u16>

Get the max length field for this column type.

Trait Implementations

impl Clone for TvpColumnType

fn clone(&self) -> TvpColumnType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TvpColumnType

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

Formats the value using the given formatter.

impl Hash for TvpColumnType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TvpColumnType

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