Trait Implementations

impl Clone for InstructionFormat

fn clone(&self) -> InstructionFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for InstructionFormat

impl Debug for InstructionFormat

fn fmt(&self, f: &mut Formatter) -> Result
