Implementations

impl<K: Clone + Eq + Hash, V> ResourcePool<K, V>

pub fn new() -> Self

pub fn get_or_init<F, E>(&self, key: K, constructor: F) -> Result<Arc<V>, E>

where F: FnOnce(K) -> Result<Arc<V>, E>,

Get a resource from the pool with the given entry map, or create a new one if it doesn’t exist using the given constructor.

Behaves such that only one resource will be created for each unique entry map at any one time.

pub fn remove(&self, key: &K)

Remove the given entry map from the pool.

Must only be called in the Drop impl of BindGroupLayout.
