A single LC-3 instruction. Except condition codes and is_immd values, all fields are set to i16 type for convenience.

Implementations

impl Instruction

pub fn from_u16(data: u16) -> Instruction

Converts a single u16 value to LC-3 instruction. Note that for some instructions that can be interpreted in multiple types (e.g. JSR/JSRR), every field will be initialized to defined bit array slice values even if it won’t be used.

Trait Implementations

impl Debug for Instruction

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

Formats the value using the given formatter.

impl Display for Instruction

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

Formats the value using the given formatter.

impl PartialEq for Instruction

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

impl Eq for Instruction

impl StructuralPartialEq for Instruction
