Struct Instruction

Source

pub struct Instruction {
    pub kind: InstKind,
    pub result_ty: Option<MirType>,
    pub metadata: InstructionMetadata,
}

Expand description

An instruction in the MIR.

Fields§

§kind: InstKind

The kind of instruction.

§result_ty: Option<MirType>

The result type (if any).

§metadata: InstructionMetadata

Metadata produced by lowering or analysis.

Implementations§

Source §
