Struct wasmer::GlobalType [−][src]
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
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.
Create a new Global variable
Usage:
use wasmer_types::{GlobalType, Type, Mutability, Value}; // An I32 constant global let global = GlobalType::new(Type::I32, Mutability::Const); // An I64 mutable global let global = GlobalType::new(Type::I64, Mutability::Var);
