Trait diesel::serialize::ToSql [] [src]

pub trait ToSql<A, DB: Backend>: Debug {
    fn to_sql<W: Write>(&self, out: &mut Output<W, DB>) -> Result;
}

Serializes a single value to be sent to the database.

The output is sent as a bind parameter, and the data must be written in the expected format for the given backend.

When possible, implementations of this trait should prefer using an existing implementation, rather than writing to out directly. (For example, if you are implementing this for an enum, which is represented as an integer in the database, you should use i32::to_sql(x, out) instead of writing to out yourself.

Any types which implement this trait should also #[derive(AsExpression)].
