Enum Operand 

pub enum Operand {
    LocalOperand {
        name: Name,
        ty: TypeRef,
    },
    ConstantOperand(ConstantRef),
    MetadataOperand,
}

Variants

LocalOperand

e.g., i32 %foo

Fields

name: Name

ty: TypeRef

ConstantOperand(ConstantRef)

includes GlobalReference for things like @foo

MetadataOperand

Implementations

impl Operand

pub fn as_constant(&self) -> Option<&Constant>

Get a reference to the Constant, if the operand is a constant; otherwise, returns None.

This allows nested matching on Operand. Instead of the following code (which doesn’t compile because you can’t directly match on ConstantRef)

if let Operand::ConstantOperand(Constant::Float(Float::Double(val))) = op

you can write this:

if let Some(Constant::Float(Float::Double(val))) = op.as_constant()

Trait Implementations

impl Clone for Operand

fn clone(&self) -> Operand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operand

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

Formats the value using the given formatter.

impl Display for Operand

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

Formats the value using the given formatter.

impl Hash for Operand

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Operand

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

impl Typed for Operand

fn get_type(&self, types: &Types) -> TypeRef

impl StructuralPartialEq for Operand
