pub fn read_observable(control_bytes: &[u8], index: u32) -> u32Expand description
Read an observable result word from a control buffer.
On a malformed or truncated control buffer this returns 0 and emits a
tracing::error! so the miss is operator-visible. Prefer
try_read_observable in new code, a silent 0 is indistinguishable from
an observable slot that was never written.
