Trait sqlx_core::encode::Encode

pub trait Encode<DB: ?Sized> where
    DB: Database, {
    fn encode(&self, buf: &mut Vec<u8>);

    fn encode_nullable(&self, buf: &mut Vec<u8>) -> IsNull { ... }
    fn size_hint(&self) -> usize { ... }
}

Encode a single value to be sent to the database.

Required methods

fn encode(&self, buf: &mut Vec<u8>)

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