pub fn atomically_result<T, E>(f: impl FnOnce() -> Result<T, E>) -> Result<T, E>where
E: Display,Expand description
Executes the given fallible function as an atomic operation.
On Ok the region is committed.
On Err the SDK calls the host trap function, which surfaces as an
uncatchable wasm trap so the failure cannot be observed by user code.
The atomic region is intentionally left open so the existing replay-time
fallback in mark_begin_operation deletes the partial inner side effects
and re-executes the block.
