Enum OpcodeMod

pub enum OpcodeMod {
    rb,
    rw,
    rd,
    ro,
}

Indicate the size of the reg used when modifying the lower three bits of the opcode byte; this corresponds to the +rb, +rw, +rd, and +ro modifiers in the reference manual.

// The `bswap` instruction extends the opcode byte:
let enc = rex([0x0F, 0xC8]).rd();
assert_eq!(enc.to_string(), "0x0F + 0xC8 +rd");

Trait Implementations

impl Clone for OpcodeMod

fn clone(&self) -> OpcodeMod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OpcodeMod

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

Formats the value using the given formatter.

impl Display for OpcodeMod

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

Formats the value using the given formatter.

impl PartialEq for OpcodeMod

fn eq(&self, other: &OpcodeMod) -> 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.
