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.
fn produces(&self) -> Option<<DB as Database>::TypeInfo>
fn size_hint(&self) -> usize
