Trait sqlx_core::encode::Encode

pub trait Encode<'q, DB: Database> {
#[must_use]    fn encode_by_ref(
        &self, 
        buf: &mut <DB as HasArguments<'q>>::ArgumentBuffer
    ) -> IsNull;

#[must_use]    fn encode(
        self,

    ) -> IsNull
    where
        Self: Sized,
    { ... }
    fn produces(&self) -> Option<DB::TypeInfo> { ... }
    fn size_hint(&self) -> usize { ... }
}

Encode a single value to be sent to the database.

Required methods

#[must_use]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.
