Struct AtomicInvPtr

source 
pub struct AtomicInvPtr<T> { /* private fields */ }
Expand description

An atomic invariant pointer. Allows reading through an immutable reference without unsafe.

Implementations§

source§

impl<Target> AtomicInvPtr<Target>

source

pub fn parts(&self) -> (usize, u64)

Read the invariant pointer into its raw parts.

source

pub fn from_parts(fote: usize, off: u64) -> Self

Construct an InvPtr from an FOT entry and an offset.

source

pub fn is_null(&self) -> bool

Check if an invariant pointer is null.

source

pub fn null() -> Self

Construct a null raw pointer.

source

pub unsafe fn inner(&mut self) -> *mut AtomicU64

Get a reference to the inner raw 64 bits of the invariant pointer.

§Safety

See this crate’s base documentation (Isolation Safety). Additionally, the caller is expected to maintain the correct semantics of invariant pointers.
