Crate grace

grace

Portable library for intercepting various kinds of shutdown signal, allowing your application to shutdown gracefully.

Windows does not have signals (although they are emulated to some extent by libc) so this crate uses the appropriate windows API functions directly to respond to interrupt and shutdown requests.

On other platforms signals are used via the signal-stack crate.

Structs

ShutdownGuard

This is the primary interface to the crate.

Enums

ShutdownType

This crate currently distinguishes two kinds of shutdown request.

Traits

Handler

This trait is implemented for functions which match the required signature for shutdown handlers.
