Implementations

impl Opcode

pub fn from_u8(v: u8) -> Self

pub fn size(self) -> usize

Instruction size in bytes.

pub fn step_count(self) -> u16

Number of steps this instruction occupies.

pub fn is_match(self) -> bool

Whether this is a Match variant.

pub fn is_extended_match(self) -> bool

Whether this is an extended Match (Match16-64).

pub fn payload_slots(self) -> usize

Payload capacity in u16 slots for extended Match variants.

Trait Implementations

impl Clone for Opcode

fn clone(&self) -> Opcode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Opcode

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

Formats the value using the given formatter.

impl PartialEq for Opcode

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