Implementations§

Source §

impl Instruction

Source

pub const fn opcode(&self) -> u8

Gets the opcode.

Source

pub const fn name<'a>(&self) -> &'a str

Gets the name of the Instruction.

Source §

impl Instruction

Source

pub fn into_raw_instruction( self, pc: ProgramCounter, cp: &mut ConstantPool, ) -> Result<RawInstruction, ToWriterError>

Lower the instruction into a raw instruction.

§Errors

See ToWriterError for details.

Trait Implementations§
