Struct Tag

#[repr(C)]
pub struct Tag { /* private fields */ }

Expand description

A WebAssembly tag.

Implementations§

§

impl Tag

pub fn new(store: impl AsContextMut, ty: &TagType) -> Result<Tag, Error>

Create a new tag instance from a given TagType.

§Panics

This function will panic when used with a Store which has a ResourceLimiterAsync (see also: Store::limiter_async. When using an async resource limiter, use [Tag::new_async] instead.

pub fn ty(&self, store: impl AsContext) -> TagType

Returns the underlying type of this tag.

§Panics

Panics if store does not own this tag.

pub fn eq(a: &Tag, b: &Tag, store: impl AsContext) -> bool

Determines whether this tag is reference equal to the other given tag in the given store.

§Panics

Panics if either tag do not belong to the given store.
