Struct OpRwInfo 

pub struct OpRwInfo {
    pub op_flags: OpRwFlags,
    pub phys_id: u8,
    pub rm_size: u8,
    pub consecutive_lead_count: u8,
    pub read_byte_mask: u64,
    pub write_byte_mask: u64,
    pub extend_byte_mask: u64,
}

Read/write information related to a single operand, used by InstRwInfo.

phys_id is always INVALID_PHYS_ID unless a physical register is required — unlike AsmJit (where value-initialization leaves it 0), asmkit keeps one “no phys id” sentinel.

Fields

op_flags: OpRwFlags

Read/write flags.

phys_id: u8

Physical register index, if required (INVALID_PHYS_ID otherwise).

rm_size: u8

Size of a possible memory operand that can replace a register operand.

consecutive_lead_count: u8

If non-zero, this is a consecutive lead register and the value describes how many registers follow.

read_byte_mask: u64

Read bit-mask where each bit represents one byte read from Reg/Mem.

write_byte_mask: u64

Write bit-mask where each bit represents one byte written to Reg/Mem.

extend_byte_mask: u64

Zero/sign extend bit-mask where each bit represents one byte written to Reg/Mem.

Implementations

impl OpRwInfo

pub const fn new() -> Self

Returns this operand info with all members reset to zero.

pub fn reset(&mut self, op_flags: OpRwFlags, register_size: u32, phys_id: u8)

Resets this operand info to op_flags, register_size, and possibly phys_id, computing full byte masks from the flags (mirrors AsmJit’s OpRWInfo::reset).

pub const fn is_read(&self) -> bool

Tests whether this operand is read from.

pub const fn is_write(&self) -> bool

Tests whether this operand is written to.

pub const fn is_read_write(&self) -> bool

Tests whether this operand is both read and written.

pub const fn is_read_only(&self) -> bool

Tests whether this operand is read-only.

pub const fn is_write_only(&self) -> bool

Tests whether this operand is write-only.
