Struct backdrop::thread::GlobalTrashThreadStrategy

pub struct GlobalTrashThreadStrategy();

Available on crate feature std only.

Strategy which sends any to-be-dropped values to a dedicated global ‘trash thread’

This trash thread is a global thread that is started using lazy_static. You probably want to control when it is started using [lazy_static::initialize(&GLOBAL_TRASH_THREAD_HANDLE)] (If you do not, it is started when it is used for the first time, meaning the very first drop will be slower.)

Sending is done using a std::sync::mpsc::sync_channel. In the current implementation, there are 10 slots available in the channel before a caller thread would block.

Also note that this global, detached, thread, will not be joined/cleaned up when your program exits. This is probably fine, though it might mean that a few final destructors are not run. But be aware that tools like e.g. Miri complain about this.
