impl Reg

pub fn apply_uses<RUM: RegUsageMapper>(&mut self, mapper: &RUM)

Apply a vreg-rreg mapping to a Reg. This is used for registers used in a read-role.

Apply a vreg-rreg mapping to a Reg. This is used for registers used in a write-role.

pub fn apply_mods<RUM: RegUsageMapper>(&mut self, mapper: &RUM)

Apply a vreg-rreg mapping to a Reg. This is used for registers used in a modify-role.

Trait Implementations

impl Clone for Reg

fn clone(&self) -> Reg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Reg

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

Formats the value using the given formatter.

impl Hash for Reg

fn hash<__H: Hasher>(&self, state: &mut __H)

    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Reg

fn cmp(&self, other: &Reg) -> Ordering

This method returns an Ordering between self and other.

#[must_use]

pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]

pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]

pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Reg> for Reg

fn eq(&self, other: &Reg) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Reg) -> bool

This method tests for !=.

This method tests less than (for self and other) and is used by the < operator.

#[must_use]

pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]

pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]

pub fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
