Struct Insn 

#[repr(C)]
pub struct Insn {
    pub op: Opcode,
    pub a: u8,
    pub b: u8,
    pub c: u8,
    pub imm: u32,
}

One register instruction. a, b, c are register operands or small counts; imm is a constant index, an absolute jump target, a key’s bits, a scope slot or an i32 literal, as the opcode’s Format says.

Fields

op: Opcode

a: u8

b: u8

c: u8

imm: u32

Implementations

impl Insn

pub const fn new(op: Opcode, a: u8, b: u8, c: u8, imm: u32) -> Insn

pub const fn int(self) -> i32

The imm field read as an i32 literal.

pub const fn short(self) -> i16

The i16 literal of an Format::AShortJump instruction.

pub const fn key(self) -> PropertyKey

The imm field read as a property key.

pub const fn site(self) -> Option<u32>

The cache site of an instruction that has one: c for GetField and SetField, b | c << 8 for the global forms, imm for New. An index into the unit’s entries of the IcStore.

pub const fn has_target(self) -> bool

Whether imm is a jump target.
