Enum Operand 

pub enum Operand {
    Register(Register),
    Immediate(i128),
    Memory(Box<MemoryOperand>),
    Label(String),
    Expression(Expr),
    RegisterList(Vec<Register>),
    LiteralPoolValue(i128),
    VectorRegister(Register, VectorArrangement),
    SvePredicate(Register, SvePredQual),
}

A resolved or unresolved operand.

Variants

Register(Register)

A register operand.

Immediate(i128)

An immediate value.

Memory(Box<MemoryOperand>)

A memory (indirect) operand.

Label(String)

A label reference (resolved later).

Expression(Expr)

An expression (e.g., label + 4).

RegisterList(Vec<Register>)

A register list (ARM {R0, R1, R4, LR}).

LiteralPoolValue(i128)

A literal pool value (LDR Xn, =0x1234). The assembler will place the constant in a nearby literal pool and emit a PC-relative LDR to load it.

VectorRegister(Register, VectorArrangement)

A vector register with arrangement specifier (AArch64 NEON/SVE). E.g., V0.4S, V1.16B, Z0.S, Z1.D.

SvePredicate(Register, SvePredQual)

SVE predicate register with qualifier (P0/M, P0/Z).

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 Default for Operand

fn default() -> Self

Returns a sentinel default value (Immediate(0)). Only used for unoccupied slots in OperandList; never exposed.

impl Display for Operand

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

Formats the value using the given formatter.

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.
