Struct UnboundedPool 

pub struct UnboundedPool<Resource, Reset> { /* private fields */ }

A resource pool with a growable number of Resources.

Implementations

impl<Resource, Reset> UnboundedPool<Resource, Reset>

pub fn new(reset_resource: Reset) -> Self

where Reset: ResetResource<Resource> + Clone,

Create a new UnboundedPool, which initially has zero Resources.

Whenever a Resource is returned to the pool, reset_resource is run on it first.

impl<Resource> UnboundedPool<Resource, ResetNothing>

pub fn new_without_reset() -> Self

Create a new UnboundedPool, which initially has zero Resources.

When a Resource is returned to the pool, it is not reset in any way.

impl<Resource, Reset> UnboundedPool<Resource, Reset>

where Resource: Default, Reset: ResetResource<Resource> + Clone,

pub fn get_default(&self) -> PooledResource<Self, Resource>

Get a Resource from the pool, returning a default Resource if none were already available in the pool.

impl<Resource, Reset: ResetResource<Resource> + Clone> UnboundedPool<Resource, Reset>

pub fn get<F>(&self, init_resource: F) -> PooledResource<Self, Resource>

where F: FnOnce() -> Resource,

Get a Resource from the pool.

pub fn pool_size(&self) -> usize

Get the total number of Resources in this pool, whether available or in-use.

pub fn available_resources(&self) -> usize

Get the number of Resources in the pool which are not currently being used.
