pub struct ScheduledThreadPool { /* private fields */ }
Expand description

A pool of threads which can run tasks at specific time intervals.

When the pool drops, all pending scheduled executions will be run, but periodic actions will not be rescheduled after that.

Implementations

Creates a new thread pool with the specified number of threads.

Panics

Panics if num_threads is 0.

Creates a new thread pool with the specified number of threads which will be named.

The substring {} in the name will be replaced with an integer identifier of the thread.

Panics

Panics if num_threads is 0.

Executes a closure as soon as possible in the pool.

Executes a closure after a time delay in the pool.

Executes a closure after an initial delay at a fixed rate in the pool.

The rate includes the time spent running the closure. For example, if the rate is 5 seconds and the closure takes 2 seconds to run, the closure will be run again 3 seconds after it completes.

Panics

If the closure panics, it will not be run again.

Executes a closure after an initial delay at a dynamic rate in the pool.

The rate includes the time spent running the closure. For example, if the return rate is 5 seconds and the closure takes 2 seconds to run, the closure will be run again 3 seconds after it completes.

Panics

If the closure panics, it will not be run again.

Executes a closure after an initial delay at a fixed rate in the pool.

In contrast to execute_at_fixed_rate, the execution time of the closure is not subtracted from the delay before it runs again. For example, if the delay is 5 seconds and the closure takes 2 seconds to run, the closure will run again 5 seconds after it completes.

Panics

If the closure panics, it will not be run again.

Executes a closure after an initial delay at a dynamic rate in the pool.

In contrast to execute_at_dynamic_rate, the execution time of the closure is not subtracted from the returned delay before it runs again. For example, if the delay is 5 seconds and the closure takes 2 seconds to run, the closure will run again 5 seconds after it completes.

Panics

If the closure panics, it will not be run again.
