SessionHandle

Struct SessionHandle 

Source
pub struct SessionHandle(/* private fields */);
Expand description

Phase 228.E — an opaque, Send handle to an Executor’s RMW session.

In the per-tier model the boot executor opens the one session and hands each spawned tier task a handle (not a borrow) so the task opens its own Executor over that same session across the RTOS task boundary. Wrapping the pub(crate) session pointer lets board crates (nros-board-posix, nros-board-freertos, …) name + move the handle without naming the session type. Obtain via Executor::session_handle; consume via Executor::open_with_session_handle.

Implementations§

Source§

impl SessionHandle

Source

pub fn into_raw(self) -> *mut c_void

Phase 274.W1 — convert to an opaque *mut c_void for C/C++ FFI.

The returned pointer encodes the session address and is valid as long as the owning executor lives. Reconstruct via Self::from_raw.

Source

pub unsafe fn from_raw(ptr: *mut c_void) -> Self

Phase 274.W1 — reconstruct a SessionHandle from an opaque pointer returned by Self::into_raw.

§Safety

ptr must be a pointer obtained from into_raw() on a SessionHandle whose underlying session is still live and owned by its original executor.
