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. Registered rollbacks will be ran on exit.

Implementations

impl Exit

pub fn new() -> Exit

pub fn register_cleanup<F>(&self, callback: F)

where F: Fn() + Send + Sync + 'static,

Registers a callback to be executed during shutdown. Callbacks are executed in registration order before the program exits.

pub fn set_ctrlc_handler(&self)

Sets the Ctrl-C signal handler for graceful shutdown.

Panics

Only one Ctrl-C handler can be registered per process. This will panic if:

• Called multiple times
• Another crate has already registered a Ctrl-C handler

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

Acquires a read lock to protect a critical section from shutdown. The shutdown handler will wait for all locks to be released.

Trait Implementations

fn clone(&self) -> Exit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)
