Struct Inst 

pub struct Inst(pub u32);

One encoded instruction.

Tuple Fields

0: u32

The 32-bit packed instruction word; layout depends on the instruction format (iABC / iABx / iAsBx / iAx / isJ).

Implementations

impl Inst

pub fn iabc(op: Op, a: u32, b: u32, c: u32, k: bool) -> Inst

Build an iABC-format instruction (A, B, C, k flag).

pub fn iabx(op: Op, a: u32, bx: u32) -> Inst

Build an iABx-format instruction (A, unsigned Bx).

pub fn iasbx(op: Op, a: u32, sbx: i32) -> Inst

Build an iAsBx-format instruction (A, signed sBx).

pub fn iax(op: Op, ax: u32) -> Inst

Build an iAx-format instruction (unsigned 25-bit Ax).

pub fn isj(op: Op, sj: i32) -> Inst

Build an isJ-format instruction (signed jump offset sJ).

pub fn op(self) -> Op

Decode the opcode field.

pub fn a(self) -> u32

Decode the A field.

pub fn k(self) -> bool

Decode the k flag (constant-vs-register selector for some ops).

pub fn b(self) -> u32

Decode the B field.

pub fn c(self) -> u32

Decode the C field.

pub fn bx(self) -> u32

Decode the unsigned Bx field.

pub fn sbx(self) -> i32

Decode the signed sBx field.

pub fn ax(self) -> u32

Decode the unsigned Ax field.

pub fn sj(self) -> i32

Decode the signed jump offset sJ.

pub fn set_sj(&mut self, sj: i32)

Patch the sJ field of a jump (forward-jump backfill).

Trait Implementations

impl Clone for Inst

fn clone(&self) -> Inst

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Inst

impl Debug for Inst

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

Formats the value using the given formatter.

impl Eq for Inst

impl PartialEq for Inst

fn eq(&self, other: &Inst) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
