BytesFetch
An in-flight bytes lookup. value raises until it is ready — await :ready() or datumhue.ready, or probe state. A lookup that finds nothing succeeds: state reads ready and value is nil — it never fails a datumhue.ready barrier.

Fields 2
| Field | Type | Access | Description |
|---|---|---|---|
state | ReadyState | read-only | Completion state of this operation. Reading it never raises or suspends; a failed operation's error surfaces at :ready(). |
value | Bytes? | read-only | The stored bytes, or nil when the key is absent. |
Methods 2
BytesFetch:on_done
methodBytesFetch:on_done(callback?: fun(handle: BytesFetch))Set, replace, or clear (pass nil) the callback run once, as a callback of its own, when this operation leaves pending. On a handle that has already left it, the callback runs after the current callback returns, never during this call. A set callback keeps the operation's outcome alive, even with no other reference to the handle, and keeps the app running until it runs or is cleared.
