Struct cranelift_codegen_meta::cdsl::operands::Operand

pub(crate) struct Operand {
    pub name: &'static str,
    pub kind: OperandKind,
    doc: Option<&'static str>,
}

An instruction operand can be an immediate, an SSA value, or an entity reference. The type of the operand is one of:

1. A ValueType instance indicates an SSA value operand with a concrete type.

2. A TypeVar instance indicates an SSA value operand, and the instruction is polymorphic over the possible concrete types that the type variable can assume.

3. An ImmediateKind instance indicates an immediate operand whose value is encoded in the instruction itself rather than being passed as an SSA value.

4. An EntityRefKind instance indicates an operand that references another entity in the function, typically something declared in the function preamble.

Fields

name: &'static str

Name of the operand variable, as it appears in function parameters, legalizations, etc.

kind: OperandKind

Type of the operand.

doc: Option<&'static str>

Implementations

impl Operand

pub fn new(name: &'static str, kind: impl Into<OperandKind>) -> Self

pub fn with_doc(self, doc: &'static str) -> Self

pub fn doc(&self) -> &str

pub fn is_value(&self) -> bool

pub fn type_var(&self) -> Option<&TypeVar>

pub fn is_varargs(&self) -> bool

pub fn is_immediate_or_entityref(&self) -> bool
