Struct cranelift_codegen::ir::instructions::ValueTypeSet

pub struct ValueTypeSet {
    pub lanes: ScalarBitSet<u16>,

A value type set describes the permitted set of types for a type variable.

Fields

lanes: ScalarBitSet<u16>

Allowed lane sizes

ints: ScalarBitSet<u8>

Allowed int widths

floats: ScalarBitSet<u8>

Allowed float widths

refs: ScalarBitSet<u8>

Allowed ref widths

dynamic_lanes: ScalarBitSet<u16>

Allowed dynamic vectors minimum lane sizes

Implementations

impl ValueTypeSet

pub fn contains(self, typ: Type) -> bool

Does typ belong to this set?

pub fn example(self) -> Type

Get an example member of this type set.

This is used for error messages to avoid suggesting invalid types.

Trait Implementations

impl Clone for ValueTypeSet

fn clone(&self) -> ValueTypeSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueTypeSet

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

Formats the value using the given formatter.

impl Default for ValueTypeSet

fn default() -> ValueTypeSet

Returns the “default value” for a type.

impl PartialEq for ValueTypeSet

fn eq(&self, other: &ValueTypeSet) -> 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.
