Struct OpaquePtr 

pub struct OpaquePtr<T>(/* private fields */);

This structure can be used to store a statically bound reference &'static T in a safe wrapper that also implements Send and Sync. These traits are implemented because the content cannot be recovered after the construction, and also because the pointer has a static lifetime.

This opaque pointer also implements Hash and Eq to be usable as a map key.

Implementations

impl<T> OpaquePtr<T>

pub const fn new(rf: &'static T) -> Self

pub fn inner(self) -> &'static T

Trait Implementations

impl<T: Clone> Clone for OpaquePtr<T>

fn clone(&self) -> OpaquePtr<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Hash for OpaquePtr<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> PartialEq for OpaquePtr<T>

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

Tests for self and other values to be equal, and is used by ==.

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

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