Struct Global 

pub struct Global { /* private fields */ }

A Global instance

Implementations

impl Global

pub fn new(global_type: GlobalType) -> Self

Create a new, zero bit-pattern initialized global from a GlobalType.

pub fn ty(&self) -> &GlobalType

Get the type of the global.

pub fn vmglobal(&self) -> NonNull<VMGlobalDefinition>

Get a pointer to the underlying definition used by the generated code.

pub fn get<T: WasmValueType>(&self, store: &dyn Any) -> Value<T>

Get a value from the global.

pub unsafe fn set<T: WasmValueType>( &self, val: Value<T>, ) -> Result<(), GlobalError>

Set a value for the global.

Safety

The caller should check that the val comes from the same store as this global.

pub unsafe fn set_unchecked<T: WasmValueType>( &self, val: Value<T>, ) -> Result<(), GlobalError>

Set a value from the global (unchecked)

Safety

The caller should check that the val comes from the same store as this global. The caller should also ensure that this global is synchronized. Otherwise, use set instead.

Trait Implementations

impl Debug for Global

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

Formats the value using the given formatter.

impl Send for Global

Safety

This is safe to send between threads because there is no-thread specific logic. TODO: look into other reasons that make something not Send

impl Sync for Global

Safety

This is safe to share between threads because it uses a Mutex internally.
