Struct cranelift_codegen::isa::registers::RegClassIndex

pub struct RegClassIndex(_);

A small reference to a register class.

Use this when storing register classes in compact data structures. The RegInfo::rc() method can be used to get the real register class reference back.

Trait Implementations

impl Clone for RegClassIndex

fn clone(&self) -> RegClassIndex

Returns a copy of the value.

Performs copy-assignment from source.

impl Copy for RegClassIndex

impl Debug for RegClassIndex

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

Formats the value using the given formatter.

impl PartialEq for RegClassIndex

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Eq for RegClassIndex

impl EntityRef for RegClassIndex

fn new(idx: usize) -> Self

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.

impl From<RegClass> for RegClassIndex

fn from(rc: RegClass) -> Self

Performs the conversion.

impl Display for RegClassIndex

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

Formats the value using the given formatter.
