Struct fpool::RoundRobinPool

pub struct RoundRobinPool<T, TCError> { /* fields omitted */ }

A Pool that uses round-robin logic to retrieve items in the pool. Can be converted into the items with the into_items() function.

Methods

impl<T, TCError> RoundRobinPool<T, TCError>

pub fn builder<F: 'static + Fn() -> Result<T, TCError>>(     pool_size: usize,     constructor: F ) -> Builder<RoundRobinPool<T, TCError>>

Get the builder for the pool.

pub fn get(&mut self) -> Result<&mut ItemHandle<T>, TCError>

Pass-through call to the Pool trait's get().

Items are re-used unless invalid, in which case they are re-constructed. If the construction fails, then the error is returned. Do not hold on to the ItemHandle reference, as it may be returned by a subsequent call on get().

pub fn size(&self) -> usize

pub fn into_items(     self ) -> impl Iterator<Item = T>

pub fn items_iter(     &self ) -> impl Iterator<Item = &T>

pub fn items_iter_mut(     &mut self ) -> impl Iterator<Item = &mut T>
