Struct wasmer_vm::store::InternalStoreHandle

#[repr(transparent)]
pub struct InternalStoreHandle<T> {
    idx: NonZeroUsize,
    marker: PhantomData<fn() -> T>,
}

Internal handle to an object owned by the current context.

Unlike StoreHandle this does not track the context ID: it is only intended to be used within objects already owned by a context.

Fields

idx: NonZeroUsize

marker: PhantomData<fn() -> T>

Implementations

impl<T: StoreObject> InternalStoreHandle<T>

pub fn new(ctx: &mut StoreObjects, val: T) -> Self

Moves the given object into a context and returns a handle to it.

pub fn get<'a>(&self, ctx: &'a StoreObjects) -> &'a T

Returns a reference to the object that this handle points to.

pub fn get_mut<'a>(&self, ctx: &'a mut StoreObjects) -> &'a mut T

Returns a mutable reference to the object that this handle points to.

pub(crate) fn index(&self) -> usize

pub(crate) fn from_index(idx: usize) -> Option<Self>

Trait Implementations

impl<T> Clone for InternalStoreHandle<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for InternalStoreHandle<T>

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

Formats the value using the given formatter.

impl<T> PartialEq for InternalStoreHandle<T>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
