[−][src]Trait sqlx::types::HasSqlType

pub trait HasSqlType<T>: Database where
    T: ?Sized, {
    fn type_info() -> Self::TypeInfo;
}

Indicates that a SQL type is supported for a database.

Required methods

`fn type_info() -> Self::TypeInfo`

Returns the canonical type information on the database for the type T.

Implementors

`impl HasSqlType<bool> for MySql`[src]

`fn type_info() -> MySqlTypeInfo`[src]

`impl HasSqlType<bool> for Postgres`[src]

`fn type_info() -> PgTypeInfo`[src]

`impl HasSqlType<f32> for Postgres`[src]

`fn type_info() -> PgTypeInfo`[src]

`impl HasSqlType<f32> for MySql`[src]

The equivalent MySQL type for f32 is FLOAT.

Note

While we added support for f32 as FLOAT for completeness, we don't recommend using it for any real-life applications as it cannot precisely represent some fractional values, and may be implicitly widened to DOUBLE in some cases, resulting in a slightly different value:

// Widening changes the equivalent decimal value, these two expressions are not equal
// (This is expected behavior for floating points and happens both in Rust and in MySQL)
assert_ne!(10.2f32 as f64, 10.2f64);

`fn type_info() -> MySqlTypeInfo`[src]

`impl HasSqlType<f64> for Postgres`[src]

`fn type_info() -> PgTypeInfo`[src]

`impl HasSqlType<f64> for MySql`[src]

The equivalent MySQL type for f64 is DOUBLE.

Note that DOUBLE is a floating-point type and cannot represent some fractional values exactly.
