Required Associated Types

type Instruction

Required Methods

fn pc(&self) -> u32

Get the current program counter.

fn pc_mut(&mut self) -> &mut u32

Get a mutable reference to the program counter.

fn get_instruction(&self, pc: u32) -> Result<&Self::Instruction>

Get the instruction at the given program counter without advancing it.

Provided Methods

fn peek_instruction(&self) -> Result<&Self::Instruction>

Peek the current instruction without advancing the program counter.

fn next_instruction(&mut self) -> Result<&Self::Instruction>

Get the current instruction and advance the program counter by 1.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
