Expand description

Encode a single value to be sent to the database.

Required Methods§

source

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§

source

fn encode(self, buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer) -> IsNull
where Self: Sized,

Writes the value of self into buf in the expected format for the database.

source

fn produces(&self) -> Option<DB::TypeInfo>

source

fn size_hint(&self) -> usize
