Struct ImmediateSlots 

pub struct ImmediateSlots(u64);

A bitmask, tracking which 4-byte slots have been written via set_immediates. Bit N corresponds to bytes [N4 .. N4+4).

Tuple Fields

0: u64

Implementations

impl ImmediateSlots

pub const fn from_raw(raw: u64) -> Self

pub const fn from_range(offset: u32, size_bytes: u32) -> Self

Compute the bitmask for a byte range [offset .. offset + size_bytes).

pub fn from_type( ty: &TypeInner, offset: u32, types: &UniqueArena<Type>, gctx: GlobalCtx<'_>, ) -> Self

Compute the slots occupied by a type at a given byte offset, excluding padding between struct members.

pub const fn contains(self, other: Self) -> bool

Returns true if self contains all bits in other.

pub const fn difference(self, other: Self) -> Self

Returns the bits in self that are not set in other.

pub fn size_for_module(module: &Module) -> u32

Returns the byte size of the var<immediate> type in a module. Zero if the module has no var<immediate>.

pub(crate) fn for_pointer( pointer: Handle<Expression>, global: Handle<GlobalVariable>, expression_arena: &Arena<Expression>, global_vars: &Arena<GlobalVariable>, types: &UniqueArena<Type>, ) -> Self

Compute the immediate slot bitmask for a pointer expression that refers to (part of) an immediate global variable.

global is the handle of the immediate global variable that this pointer derives from (obtained from assignable_global).

Trait Implementations

impl BitOr for ImmediateSlots

type Output = ImmediateSlots

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl BitOrAssign for ImmediateSlots

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl Clone for ImmediateSlots

fn clone(&self) -> ImmediateSlots

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImmediateSlots

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

Formats the value using the given formatter.

impl Default for ImmediateSlots

fn default() -> ImmediateSlots

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ImmediateSlots

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ImmediateSlots

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

Formats the value using the given formatter.

impl PartialEq for ImmediateSlots

fn eq(&self, other: &ImmediateSlots) -> 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 Serialize for ImmediateSlots

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
