Trait sqlx::Encode

pub trait Encode<'q, DB>
where
    DB: Database,
{
    // Required method
    fn encode_by_ref(
        &self,
        buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer

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

Encode a single value to be sent to the database.

Required Methods

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

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.

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

fn size_hint(&self) -> usize
