Enum rustc_codegen_ssa::mir::operand::OperandValue

pub enum OperandValue<V> {
    Ref(V, Option<V>, Align),
    Immediate(V),
    Pair(V, V),
}

The representation of a Rust value. The enum variant is in fact uniquely determined by the value’s type, but is kept as a safety check.

Variants

Ref(V, Option<V>, Align)

A reference to the actual operand. The data is guaranteed to be valid for the operand’s lifetime. The second value, if any, is the extra data (vtable or length) which indicates that it refers to an unsized rvalue.

Immediate(V)

A single LLVM value.

Pair(V, V)

A pair of immediate LLVM values. Used by fat pointers too.

Trait Implementations

impl<V: Clone> Clone for OperandValue<V>

fn clone(&self) -> OperandValue<V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: Debug> Debug for OperandValue<V>

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

Formats the value using the given formatter.

impl<V: Copy> Copy for OperandValue<V>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
