Variants

R

rd, rs1, rs2 (OP / OP-32). aux = funct7.

I

IShift32

rd, rs1, shamt5 (W shift). aux = funct7.

Store

rs1(base), rs2(val), imm12 (STORE).

Branch

Trait Implementations

impl Clone for Fmt

fn clone(&self) -> Fmt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fmt

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

Formats the value using the given formatter.

impl PartialEq for Fmt

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