Motivation
When continuously handling Ctrl+C using
tokio::signal::ctrl_c()
in a loop, the handler gets registered and deregistered on each iteration. It is useful to instead have an infinite stream of events. This is already possible with signals on Unix andtokio::signal::windows::ctrl_break()
on Windows, buttokio::signal::windows::ctrl_c()
is currently private.Solution
ctrl_c()
public, analogous to the already publicctrl_break()
.tokio::signal::windows::Event
in the module documentation. ExposingEvent
would be an alternative solution here, but the chosen approach seems more consistent with the existing API.
