Implementations

impl InstructionCategory

pub fn from_opcode_byte(b: u8) -> Self

Look up category from raw opcode byte via static table (O(1), no branching).

Trait Implementations

impl Clone for InstructionCategory

fn clone(&self) -> InstructionCategory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InstructionCategory

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

Formats the value using the given formatter.

impl PartialEq for InstructionCategory

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