Struct regalloc2::SpillSlot

pub struct SpillSlot { /* private fields */ }

A spillslot is a space in the stackframe used by the allocator to temporarily store a value.

The allocator is responsible for allocating indices in this space, and will specify how many spillslots have been used when the allocation is completed.

Implementations

impl SpillSlot

pub const MAX: usize = 16_777_215usize

The maximum spillslot index.

pub fn new(slot: usize, class: RegClass) -> Self

Create a new SpillSlot of a given class.

pub fn index(self) -> usize

Get the spillslot index for this spillslot.

pub fn class(self) -> RegClass

Get the class for this spillslot.

pub fn plus(self, offset: usize) -> Self

Get the spillslot offset slots away.

pub fn invalid() -> Self

Get the invalid spillslot, used for initializing data structures.

pub fn is_invalid(self) -> bool

Is this the invalid spillslot?

pub fn is_valid(self) -> bool

Is this a valid spillslot (not SpillSlot::invalid())?

Trait Implementations

impl Clone for SpillSlot

fn clone(&self) -> SpillSlot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SpillSlot

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

Formats the value using the given formatter.

impl Display for SpillSlot

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

Formats the value using the given formatter.

impl Hash for SpillSlot

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SpillSlot

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<SpillSlot> for SpillSlot

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<SpillSlot> for SpillSlot

fn partial_cmp(&self, other: &SpillSlot) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

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

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

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

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

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

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

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