Struct twizzler_object::ptr::InvPtr

#[repr(transparent)]
pub struct InvPtr<T> { /* private fields */ }

The raw invariant pointer, containing just a 64-bit packed FOT entry and offset.

Implementations

impl<Target> InvPtr<Target>

pub unsafe fn parts_unguarded(&self) -> (usize, u64)

Read the invariant pointer into its raw parts.

Safety

See this crate’s base documentation (Isolation Safety).

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

Read the invariant pointer into its raw parts.

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

Construct an InvPtr from an FOT entry and an offset.

pub unsafe fn is_null_unguarded(&self) -> bool

Check if an invariant pointer is null.

Safety

See this crate’s base documentation (Isolation Safety).

pub fn is_null(&mut self) -> bool

Check if an invariant pointer is null.

pub fn null() -> Self

Construct a null raw pointer.

pub unsafe fn raw_inner(&mut self) -> *mut u64

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.
