Struct wasmer::GlobalType

pub struct GlobalType {
    pub ty: Type,
    pub mutability: Mutability,
}

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

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.

pub fn new(ty: Type, mutability: Mutability) -> GlobalType

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);
