pub struct TinyInt;

The tiny integer SQL type.

This is only available on MySQL. Keep in mind that diesel print-schema will see TINYINT(1) as Bool, not TinyInt.

impl Clone for TinyInt

fn clone(&self) -> TinyInt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TinyInt

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

Formats the value using the given formatter.

impl Default for TinyInt

fn default() -> TinyInt

Returns the “default value” for a type.

impl FromSql<TinyInt, Mysql> for i8

Available on crate feature mysql_backend only.

fn from_sql(value: MysqlValue<'_>) -> Result<Self>

See the trait documentation.

fn from_nullable_sql(bytes: Option<DB::RawValue<'_>>) -> Result<Self>

A specialized variant of from_sql for handling null values.

impl HasSqlType<TinyInt> for Mysql

fn metadata(_: &mut ()) -> MysqlType

Fetch the metadata for the given type

impl QueryId for TinyInt

const HAS_STATIC_QUERY_ID: bool = true

Can the SQL generated by Self be uniquely identified by its type?

type QueryId = TinyInt

A type which uniquely represents Self in a SQL query.

fn query_id() -> Option<TypeId>

Returns the type id of Self::QueryId if Self::HAS_STATIC_QUERY_ID. Returns None otherwise.

impl SqlType for TinyInt

type IsNull = NotNull

Is this type nullable?

impl ToSql<TinyInt, Mysql> for i8

Available on crate feature mysql_backend only.

fn to_sql<'b>(&'b self, out: &mut Output<'b, '_, Mysql>) -> Result

See the trait documentation.
