Struct mc_core::util::OpaquePtr

#[repr(transparent)]
pub struct OpaquePtr<T>(_);

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>
