pub struct Instruction(/* private fields */);

Implementations

impl Instruction

pub fn new(raw: u32) -> Self

pub fn raw(&self) -> u32

pub fn opcode(&self) -> u8

The instruction’s primary opcode.

pub fn funct(&self) -> u8

For SPECIAL (00), opcode instructions (R-Type), this returns the function code, or secondary opcode.

pub fn rs(&self) -> usize

The index of the rs (source) register.Like forrtandrd`, it is not always a source register.

pub fn rt(&self) -> usize

The index of the rt (target) register.

pub fn rd(&self) -> usize

The index of the rd (destination) register.

pub fn shamt(&self) -> usize

The numerical value of the shift amount. 0 to 31.

pub fn simm16(&self) -> i32

The value of the 16-bit immediate value, sign-extended to 32 bits.

pub fn imm16(&self) -> u32

The value of the 16-bit immediate value, zero-extended to 32 bits.

pub fn jump_target(&self) -> u32

The value of the 26-bit jump target field, zero-extended to 32 bits. You must shift this value left by 2 bits to get the actual address.

pub fn cop_execute(&self) -> bool

This bit is set if the instruction must be executed by a coprocessor.

pub fn cop_funct(&self) -> u8

For non cop-execute instructions, this is the secondary opcode, to distinguish between mfc, mtc, etc…

pub fn cop_instruction(&self) -> u32

The raw coprocessor instruction code, which is the lower 25 bits. The meaning is coprocessor-specific.
