Trait Implementations

impl<Type: Clone> Clone for Reg<Type>

fn clone(&self) -> Reg<Type>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Type> Debug for Reg<Type>

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

Formats the value using the given formatter.

impl<Type> Display for Reg<Type>

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

Formats the value using the given formatter.

impl<Type> From<EReg<u64>> for Reg<Type>

fn from(reg: EReg<u64>) -> Self

Converts to this type from the input type.

impl<Type> PartialEq for Reg<Type>

fn eq(&self, other: &Self) -> 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 Register for Reg<u32>

const N: usize = 32usize

The number of general purpose registers.

type Type = u32

Register type.

fn from_bits(bits: u8) -> Option<Self>

Create a register from its bit representation

impl Register for Reg<u64>

const N: usize = 32usize

The number of general purpose registers.

type Type = u64

Register type.

fn from_bits(bits: u8) -> Option<Self>

Create a register from its bit representation

impl<Type: Copy> Copy for Reg<Type>

impl<Type> Eq for Reg<Type>
