Struct HostTreePointer

source

pub struct HostTreePointer<T> { /* private fields */ }

Expand description

A pointer to an object that is safe to dereference from any thread, if the Host lock for the specified host is held.

Implementations§

source §

impl<T> HostTreePointer<T>

source

pub fn new_for_host(host_id: HostId, ptr: *mut T) -> Self

Create a pointer that may only be accessed when the host with id host_id is active.

source

pub fn new(ptr: *mut T) -> Self

Create a pointer that may only be accessed when the current host is active.

source

pub unsafe fn ptr(&self) -> *mut T

Get the pointer.

Panics if the configured host is not active.

§Safety

Pointer must only be dereferenced while the configures Host is still active, in addition to the normal safety requirements for dereferencing a pointer.

source

pub unsafe fn ptr_with_host(&self, host: &Host) -> *mut T

Get the pointer.

Panics if host is not the one associated with self.

§Safety

Pointer must only be dereferenced while the configures Host is still active, in addition to the normal safety requirements for dereferencing a pointer.

source

pub unsafe fn ptr_unchecked(&self) -> *mut T

Get the pointer without checking the active host.

§Safety

Pointer must only be dereferenced while the configures Host is still active, in addition to the normal safety requirements for dereferencing a pointer.
