Trait atomic_traits::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.

Object Safety

This trait is not object safe.
