Struct VMGlobalImport

#[repr(C)]pub struct VMGlobalImport {
    pub definition: NonNull<VMGlobalDefinition>,
    pub handle: InternalStoreHandle<VMGlobal>,
}

Expand description

The fields compiled code needs to access to utilize a WebAssembly global variable imported from another instance.

Fields§

§definition: NonNull<VMGlobalDefinition>

A pointer to the imported global variable description.

§handle: InternalStoreHandle<VMGlobal>

A handle to the Global that owns the global description.

Trait Implementations§

impl Clone for VMGlobalImport

fn clone(&self) -> VMGlobalImport

Returns a copy of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Send for VMGlobalImport

§Safety

This data is safe to share between threads because it’s plain data that is the user’s responsibility to synchronize. Additionally, all operations on from are thread-safe through the use of a mutex in VMGlobal.

impl Sync for VMGlobalImport

§Safety

This data is safe to share between threads because it’s plain data that is the user’s responsibility to synchronize. And because it’s Clone, there’s really no difference between passing it by reference or by value as far as correctness in a multi-threaded context is concerned.
