Struct ThreadGuard 

pub struct ThreadGuard<T>(/* private fields */);

A thread guard.

A thread guard that automatically joins the thread in the destructor.

Additionally, custom pre-actions and post-actions can be defined to execute before and after thread joining, respectively. The thread can also be explicitly joined using the join method. In this case, the pre-action is executed before the join, and the thread result is returned to the caller.

Implementations

impl<T> ThreadGuard<T>

pub fn new(handle: JoinHandle<T>) -> Self

Creates a new ThreadGuard.

pub fn with_pre_action<U, F>(handle: JoinHandle<T>, pre_action: F) -> Self

where for<'a> F: FnOnce(&JoinHandle<T>) -> U + Send + 'a,

Creates a new ThreadGuard with the specified pre-action.

pub fn with_post_action<F>(handle: JoinHandle<T>, post_action: F) -> Self

where for<'a> F: FnOnce(ThreadResult<T>) + Send + 'a,

Creates a new ThreadGuard with the specified post-action.

pub fn with_actions<U, F, G>( handle: JoinHandle<T>, pre_action: F, post_action: G, ) -> Self

where for<'a> F: FnOnce(&JoinHandle<T>) -> U + Send + 'a, for<'a> G: FnOnce(U, ThreadResult<T>) + Send + 'a,

Creates a new ThreadGuard with the specified pre-action and post-action.

pub fn join(self) -> ThreadResult<T>

Joins the guarded thread.
