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§

source§

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.

source

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);
