Struct cranelift_wasm::Global

pub struct Global {
    pub wasm_ty: WasmType,
    pub mutability: bool,
    pub initializer: GlobalInit,
}

A WebAssembly global.

Note that we record both the original Wasm type and the Cranelift IR type used to represent it. This is because multiple different kinds of Wasm types might be represented with the same Cranelift IR type. For example, both a Wasm i64 and a funcref might be represented with a Cranelift i64 on 64-bit architectures, and when GC is not required for func refs.

Fields

wasm_ty: WasmType

The Wasm type of the value stored in the global.

mutability: bool

A flag indicating whether the value may change at runtime.

initializer: GlobalInit

The source of the initial value.

Implementations

impl Global

pub fn new(ty: GlobalType, initializer: GlobalInit) -> Result<Global, WasmError>

Creates a new Global type from wasmparser’s representation.

Trait Implementations

impl Clone for Global

fn clone(&self) -> Global

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Global

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Global

fn deserialize<__D>(
    __deserializer: __D
) -> Result<Global, <__D as Deserializer<'de>>::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Hash for Global

fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,
