Struct wasmer_vm::VMExternRef

source · [−]

#[repr(transparent)]
pub struct VMExternRef(_);

Expand description

This type does not do reference counting automatically, reference counting can be done with Self::ref_clone and Self::ref_drop.

Implementations

source

impl VMExternRef

source

pub fn is_null(&self) -> bool

Checks if the given ExternRef is null.

source

pub const fn null() -> VMExternRef

New null extern ref

source

pub fn new<T>(value: T) -> VMExternRef where
T: 'static + Any + Send + Sync,

Make a new extern reference

source

pub fn downcast<T>(&self) -> Option<&T> where
T: 'static + Any + Send + Sync,

Try to downcast to the given value

source

pub fn ref_inc_by(&self, val: usize)

A low-level function to increment the strong-count a given number of times.

This is used as an optimization when implementing some low-level VM primitives. If you’re using this type directly for whatever reason, you probably want Self::ref_clone instead.

source

pub fn ref_clone(&self) -> VMExternRef

A deep copy of the reference, increments the strong count.

source

pub fn ref_drop(&mut self)

Does an inner drop, decrementing the strong count
