One decoded operand; which fields are meaningful depends on kind.

Fields

kind: u8

Semantic kind (0 reg, 1 mem, 2 imm, 3 near, 4 far).

idx: u8

Original operand slot index (feature bits are keyed by it).

offb: u8

Raw op_t::offb: the operand’s byte offset within the encoded instruction.

data_type: u8

Raw op_dtype_t.

access: u8

Access bits: bit0 read, bit1 written.

scale: u8

Memory index scale multiplier (1/2/4/8).

reg: RegisterData

Register (kind = reg). Named reg, not register (a C++ keyword).

base: RegisterData

Memory base register (kind = mem).

index: RegisterData

Memory index register (kind = mem).

disp: i64

Memory displacement (kind = mem).

value: u64

Immediate value (kind = imm) or far offset (kind = far).

addr: u64

Near target, or memory static target / BADADDR (kind = near/mem).

sel: u16

Far selector (kind = far).

broadcast: u8

EVEX embedded-broadcast factor N of a {1toN} memory operand, as IDA renders it, else 0.

Trait Implementations

impl ExternType for OperandData

type Kind = Trivial

Either cxx::kind::Opaque or cxx::kind::Trivial.

type Id

A type-level representation of the type’s C++ namespace and type name.
