Enum wasmtime_environ::VMGcKind

#[repr(u32)]
pub enum VMGcKind {
    ExternRef = 0,
}

This is accessed from Wasm JIT code.

Variants

An externref holding some kind of host data.

Implementations

impl VMGcKind

pub const MASK: u32 = 3_221_225_472u32

Mask this value with a u32 to turn it into a valid VMGcKind.

pub const UNUSED_MASK: u32 = 1_073_741_823u32

Mask this value with a u32 that potentially contains a VMGcKind to get the bits that VMGcKind doesn’t use.

pub const fn from_u32(val: u32) -> VMGcKind

Convert the given value into a VMGcKind by masking off the unused bits.

Trait Implementations

impl Clone for VMGcKind

fn clone(&self) -> VMGcKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VMGcKind

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

Formats the value using the given formatter.

impl PartialEq for VMGcKind

fn eq(&self, other: &VMGcKind) -> 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.
