Struct wasmtime_environ::StackMap

source · [−]

pub struct StackMap { /* private fields */ }

Expand description

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

source

impl StackMap

source

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

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

source

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

Returns a specified bit.

source

pub fn mapped_words(&self) -> u32

Returns the number of words represented by this stack map.
