[−][src]Struct grace::ShutdownGuard
This is the primary interface to the crate.
Construct an instance of this type to begin intercepting shutdown requests. When the guard is dropped, shutdown requests will no longer be intercepted.
There are several constructors to simplify common usage patterns.
Implementations
impl<'a> ShutdownGuard<'a>[src]
pub fn new<H: Handler>(types: &'a [ShutdownType], handler: H) -> Self[src]
Call a user-defined function whenever a shutdown is requested.
pub fn new_channel(types: &'a [ShutdownType]) -> (Self, Receiver<ShutdownType>)[src]
Send on an mpsc channel whenever a shutdown is requested.
pub fn forget(self)[src]
Forget this guard, leaving the shutdown handler installed for the lifetime of the program.
