Struct cranelift_codegen::ir::entities::StackSlot

pub struct StackSlot(_);

An opaque reference to a stack slot.

Stack slots represent an address on the call stack.

StackSlots can be created with FunctionBuilder::create_stackslot.

StackSlots are most often used with stack_addr, stack_load, and stack_store.

Methods

impl StackSlot

pub fn from_u32(x: u32) -> Self

Return the underlying index value as a u32.

pub fn as_u32(self) -> u32

Return the underlying index value as a u32.

impl StackSlot

pub fn with_number(n: u32) -> Option<Self>

Create a new stack slot reference from its number.

This method is for use by the parser.

Trait Implementations

impl Clone for StackSlot

fn clone(&self) -> StackSlot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for StackSlot

impl Debug for StackSlot

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

Formats the value using the given formatter.

impl Display for StackSlot

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

Formats the value using the given formatter.

impl EntityRef for StackSlot

fn new(index: usize) -> Self

Create a new entity reference from a small integer. This should crash if the requested index is not representable.

fn index(self) -> usize

Get the index that was used to create this entity reference.

impl Eq for StackSlot

impl From<StackSlot> for AnyEntity

fn from(r: StackSlot) -> Self

Performs the conversion.

impl Hash for StackSlot

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, 

Feeds a slice of this type into the given [Hasher].

impl Index<StackSlot> for StackSlots

type Output = StackSlotData

The returned type after indexing.

fn index(&self, ss: StackSlot) -> &StackSlotData

Performs the indexing (container[index]) operation.

impl IndexMut<StackSlot> for StackSlots

fn index_mut(&mut self, ss: StackSlot) -> &mut StackSlotData

Performs the mutable indexing (container[index]) operation.

impl PartialEq<StackSlot> for StackSlot

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

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

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

This method tests for !=.

impl ReservedValue for StackSlot

fn reserved_value() -> StackSlot

Create an instance of the reserved value.
