}Expand description
Encode a single value to be sent to the database.
Required Methods§
Sourcefn encode_by_ref(
&self,
buf: &mut <DB as Database>::ArgumentBuffer<'q>,
) -> Result<IsNull, Box<dyn Error + Sync + Send>>
fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer<'q>, ) -> Result<IsNull, Box<dyn Error + Sync + Send>>
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 Database>::ArgumentBuffer<'q>,
) -> Result<IsNull, Box<dyn Error + Sync + Send>>where
Self: Sized,
fn encode(
self,
buf: &mut <DB as Database>::ArgumentBuffer<'q>,
) -> Result<IsNull, Box<dyn Error + Sync + Send>>where
Self: Sized,
Writes the value of self into buf in the expected format for the database.
