Struct wasmer::GlobalType
source · pub struct GlobalType {
pub ty: Type,
pub mutability: Mutability,
}
Expand description
WebAssembly global.
Fields
ty: Type
The type of the value stored in the global.
mutability: Mutability
A flag indicating whether the value may change at runtime.
Implementations
sourceimpl GlobalType
impl GlobalType
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.
sourcepub fn new(ty: Type, mutability: Mutability) -> GlobalType
pub fn new(ty: Type, mutability: Mutability) -> GlobalType
Create a new Global variable
Usage:
use wasmer_types::{GlobalType, Type, Mutability};
// An I32 constant global
let global = GlobalType::new(Type::I32, Mutability::Const);
// An I64 mutable global
let global = GlobalType::new(Type::I64, Mutability::Var);
