Struct GlobalType 

pub struct GlobalType { /* private fields */ }

A WebAssembly global descriptor.

This type describes an instance of a global in a WebAssembly module. Globals are local to an Instance and are either immutable or mutable.

Implementations

impl GlobalType

pub fn new(content: ValType, mutability: Mutability) -> GlobalType

Available on crate feature runtime only.

Creates a new global descriptor of the specified content type and whether or not it’s mutable.

pub fn content(&self) -> &ValType

Available on crate feature runtime only.

Returns the value type of this global descriptor.

pub fn mutability(&self) -> Mutability

Available on crate feature runtime only.

Returns whether or not this global is mutable.

pub fn default_value(&self, store: impl AsContextMut) -> Result<RuntimeGlobal>

Available on crate feature runtime only.

Construct a new global import with this type’s default value.

This creates a host Global in the given store initialized to the type’s zero/null default (e.g. 0 for numeric globals, null_ref for refs).

impl From<GlobalType> for ExternType

Available on crate feature runtime only.

fn from(ty: GlobalType) -> ExternType

impl Hash for GlobalType

Available on crate feature runtime only.

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.
