Trait Encode 

pub trait Encode<'q, DB: Database> {
    // Required method
    fn encode_by_ref(
        &self,
        buf: &mut <DB as Database>::ArgumentBuffer,
    ) -> Result<IsNull, BoxDynError>;

    // Provided methods
    fn encode(
        self,
        buf: &mut <DB as Database>::ArgumentBuffer,
    ) -> Result<IsNull, BoxDynError>
       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

fn encode_by_ref( &self, buf: &mut <DB as Database>::ArgumentBuffer, ) -> Result<IsNull, BoxDynError>

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 Database>::ArgumentBuffer, ) -> Result<IsNull, BoxDynError>

where Self: Sized,

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

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

fn size_hint(&self) -> usize
