Struct wasmtime_environ::StackMap

pub struct StackMap { /* fields omitted */ }

A map for determining where live GC references live in a stack frame.

Note that this is currently primarily documented as cranelift’s binemit::StackMap, so for detailed documentation about this please read the docs over there.

Implementations

impl StackMap

pub fn new(mapped_words: u32, bits: impl Iterator<Item = u32>) -> StackMap

Creates a new StackMap, typically from a preexisting binemit::StackMap.

pub fn get_bit(&self, bit_index: usize) -> bool

Returns a specified bit.

pub fn mapped_words(&self) -> u32

Returns the number of words represented by this stack map.

Trait Implementations

impl Clone for StackMap

fn clone(&self) -> StackMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StackMap

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StackMap

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl PartialEq<StackMap> for StackMap

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