Struct wasmtime_runtime::SendSyncPtr

pub struct SendSyncPtr<T: ?Sized>(/* private fields */);

A helper type in Wasmtime to store a raw pointer to T while automatically inferring the Send and Sync traits for the container based on the properties of T.

Implementations

impl<T: ?Sized> SendSyncPtr<T>

pub fn new(ptr: NonNull<T>) -> SendSyncPtr<T>

Creates a new pointer wrapping the non-nullable pointer provided.

pub fn as_ptr(&self) -> *mut T

Returns the underlying raw pointer.

pub unsafe fn as_ref<'a>(&self) -> &'a T

Unsafely assert that this is a pointer to valid contents and it’s also valid to get a shared reference to it at this time.

pub unsafe fn as_mut<'a>(&mut self) -> &'a mut T

Unsafely assert that this is a pointer to valid contents and it’s also valid to get a mutable reference to it at this time.

pub fn as_non_null(&self) -> NonNull<T>

Returns the underlying NonNull<T> wrapper.

pub fn cast<U>(&self) -> SendSyncPtr<U>

Cast this to a pointer to a U.

impl<T> SendSyncPtr<[T]>

pub fn len(&self) -> usize

Returns the slice’s length component of the pointer.

Trait Implementations

impl<T: ?Sized> Clone for SendSyncPtr<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: ?Sized> Debug for SendSyncPtr<T>

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

Formats the value using the given formatter.

impl<T: ?Sized, U> From<U> for SendSyncPtr<T>

where U: Into<NonNull<T>>,

fn from(ptr: U) -> SendSyncPtr<T>

Converts to this type from the input type.

impl<T: ?Sized> Hash for SendSyncPtr<T>

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: ?Sized> PartialEq for SendSyncPtr<T>

fn eq(&self, other: &SendSyncPtr<T>) -> 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.

impl<T: ?Sized> Pointer for SendSyncPtr<T>

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

Formats the value using the given formatter.

impl<T: ?Sized> Copy for SendSyncPtr<T>
