Trait FromPtr 

pub trait FromPtr: Atomic {
    // Required method
    unsafe fn from_ptr<'a>(ptr: *mut Self::Type) -> &'a Self;
}

Creates a new atomic type from a pointer.

Required Methods

unsafe fn from_ptr<'a>(ptr: *mut Self::Type) -> &'a Self

Creates a new atomic type from a pointer.

Safety

• ptr must be aligned to align_of::<Self>() (note that on some platforms this can be bigger than align_of::<Self::Type>()).
• ptr must be [valid] for both reads and writes for the whole lifetime 'a.
• You must adhere to the [Memory model for atomic accesses]. In particular, it is not allowed to mix atomic and non-atomic accesses, or atomic accesses of different sizes, without synchronization.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
