pub struct SharedPool<T> { /* private fields */ }Expand description
This is a simple generic wrapper around Pool to make it a bit easier to use
Implementations§
Sourcepub fn new(factory: Box<dyn Fn() -> T + Send + Sync>, count: usize) -> Self
pub fn new(factory: Box<dyn Fn() -> T + Send + Sync>, count: usize) -> Self
Create a new shared pool with the given MAX_POOL_STACKS count.
Pool stacks are a way to reduce contention on the pool for non-owners. To reduce contention as much as possible, we ideally want to have a one-to-one ratio from the number of CPUs to the number of pool stacks. This function will create a pool with the number of stacks set to the nearest power of 2 greater than or equal to the given count, until 64. Anything greater than 32 will use 64. Anything less than or equal to 4 will use 4.
Examples: * new(, 7) -> 8 * new(, 16) -> 16 * new(_, 42) -> 64
pub fn get(&self) -> Box<dyn AutoStacksSizeGuard<T> + '_>
