A WebAssembly tag.

Implementations

impl Tag

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

Available on crate feature runtime only.

Create a new tag instance from a given TagType.

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

Available on crate feature runtime only.

Returns the underlying type of this tag.

Panics

Panics if store does not own this tag.

pub fn debug_index_in_store(&self) -> u64

Available on crate features runtime and debug only.

Returns a stable identifier for this tag within its store.

This allows distinguishing tags when introspecting them e.g. via debug APIs.

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

Available on crate feature runtime only.

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.
