Trait diesel::types::ToSql

pub trait ToSql<A, DB: Backend + HasSqlType<A>>: Debug {
    fn to_sql<W: Write>(
        &self, 
        out: &mut W
    ) -> Result<IsNull, Box<Error + Send + Sync>>;
}

Serializes a single value to be sent to the database. The output will be included as a bind parameter, and is expected to be the binary format, not text.

Required Methods

fn to_sql<W: Write>(
    &self,
    out: &mut W
) -> Result<IsNull, Box<Error + Send + Sync>>
