Struct Pool

Source
pub struct Pool<T> { /* private fields */ }
Expand description

Container for objects that can be taken out.

Implementations§

Source§

impl<T> Pool<T>

Source

pub fn new(items: impl IntoIterator<Item = T>) -> Self

Construct a new Pool with the items from the iterator.

Source

pub fn take(&self) -> Returnable<'_, T>

Remove an item from the pool, this will take the “oldest” item.

The item will automatically get returned to the pool when the smart pointer is dropped.

There is no “resetting” that is common in other frameworks. You need to perform any resetting on your own.
