Variables defined as `_` only are released immediately; see compile error:
error: non-binding let on a synchronization lock
--> libs/hbb_common/src/config.rs:798:13
|
798 | let _ = CONFIG.read().unwrap(); // for lock
| ^ ^^^^^^^^^^^^^^^^^^^^^^ this binding will immediately drop the value assigned to it
| |
| this lock is not assigned to a binding and is immediately dropped
|
= note: `#[deny(let_underscore_lock)]` on by default
By appending a phony suffix to the variable name, the lock stays in scope.
