pub struct RefCache<'c, C: SparseContainer> { /* private fields */ }

Implementations

impl<'c, C: SparseContainer> RefCache<'c, C>

pub fn new( cache: &'c mut C, f: &'c (dyn Fn(&mut Self, &C::Input) -> C::Output + Send), ) -> Self

Trait Implementations

impl<'c, C> FnCache<<C as SparseContainer>::Input, <C as SparseContainer>::Output> for RefCache<'c, C>

where C: SparseContainer,

fn get(&mut self, input: C::Input) -> &C::Output

Retrieve a value stored in the cache. If the value does not yet exist in the cache, the function is called, and the result is added to the cache before returning it.

impl<'c, C> FnCacheMany<<C as SparseContainer>::Input, <C as SparseContainer>::Output> for RefCache<'c, C>

where C: SparseContainer, C::Input: Clone,

fn get_many<const N: usize>(&mut self, inputs: [C::Input; N]) -> [&C::Output; N]

Retrieve multiple values stored in the cache. If any of the values do not yet exist, the function is called, and the result is added to the cache before returning them.
