}Expand description
Encode a single value to be sent to the database.
Required Methods§
sourcefn encode_by_ref(
&self,
buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer
) -> IsNull
fn encode_by_ref( &self, buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer ) -> IsNull
Writes the value of self into buf without moving self.
Where possible, make use of encode instead as it can take advantage of re-using
memory.
Provided Methods§
sourcefn encode(self, buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer) -> IsNullwhere
Self: Sized,
fn encode(self, buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer) -> IsNullwhere
Self: Sized,
Writes the value of self into buf in the expected format for the database.
