Host callback table.

Fields

send_result: unsafe extern "C" fn(host_ctx: *mut c_void, sid: u64, status: NrStatus, payload: NrVec<u8>) -> NrStatus

Delivers a response the host copies into its own memory. The payload may be borrowed (owned = 0); an owned payload is freed through its drop_fn after the copy.

send_result_owned: unsafe extern "C" fn(host_ctx: *mut c_void, sid: u64, status: NrStatus, payload: NrOwnedBytes) -> NrStatus

Delivers a response without a host-side copy; the host takes ownership of the payload and calls its release exactly once.

acquire_result_buffer: unsafe extern "C" fn(host_ctx: *mut c_void, sid: u64, capacity: u64) -> NrBufferLease

Leases a host-owned buffer of at least capacity bytes for the response to sid. Fails (null ptr) for unknown sids, streaming sids, and sids that already hold an outstanding lease.

commit_result_buffer: unsafe extern "C" fn(host_ctx: *mut c_void, sid: u64, status: NrStatus, token: u64, initialized_len: u64) -> NrStatus

Commits the leased buffer as the response to sid: initialized_len bytes (at most the leased capacity) must have been written. On Ok the buffer now belongs to the host; on Invalid with a live lease (bad token or oversized length) the lease stays valid and may be committed again.
