Struct Exit 

pub struct Exit(/* private fields */);

Graceful shutdown coordinator for ensuring data consistency during program exit.

Uses a read-write lock to coordinate between operations and shutdown signals (e.g., Ctrl-C). Operations hold read locks during critical sections, preventing shutdown until they complete.

Implementations

impl Exit

pub fn new() -> Self

pub fn set_ctrlc_handler(&self)

Only one handler throughout the program (and among all crates) can be set at once

Make sure that no other crate sets one

pub fn lock(&self) -> RwLockReadGuard<'_, ()>
