Struct twizzler_runtime_api::ObjectHandle

pub struct ObjectHandle {
    pub internal_refs: NonNull<InternalHandleRefs>,
    pub id: ObjID,
    pub flags: MapFlags,
    pub start: *mut u8,
    pub meta: *mut u8,
}

A handle to an internal object. This has similar semantics to Arc, but since this crate must be #[no_std], we need to implement refcounting ourselves.

Fields

internal_refs: NonNull<InternalHandleRefs>

Pointer to refcounter.

id: ObjID

The ID of the object.

flags: MapFlags

The flags of this handle.

start: *mut u8

A pointer to the object’s start (null-page, not base).

meta: *mut u8

A pointer to the object’s metadata.
