[−][src]Trait sqlx::Type

pub trait Type<DB> where
    DB: Database, {
    fn type_info() -> <DB as Database>::TypeInfo;
}

Indicates that a SQL type is supported for a database.

Required methods

fn type_info() -> <DB as Database>::TypeInfo

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

Implementations on Foreign Types

impl Type<Postgres> for f32[src]

impl Type<MySql> for f32[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);
