		Package fips140cache provides a weak map that associates the lifetime of
		values with the lifetime of keys.
		
		It can be used to associate a precomputed value (such as an internal/fips140
		PrivateKey value, which in FIPS 140-3 mode may have required an expensive
		pairwise consistency test) with a type that doesn't have private fields (such
		as an ed25519.PrivateKey), or that can't be safely modified because it may be
		concurrently copied (such as an ecdsa.PrivateKey).
Package-Level Type Names (only one)

	/* sort by: alphabet | popularity */
	 type Cache[K, V] (struct)

		Type Parameters:
			K: any
			V: any

		Methods (only one)
			(*Cache[K, V]) Get(k *K, new func() (*V, error), check func(*V) bool) (*V, error)
				Get returns the result of new, for an associated key k.
				
				If Get was called with k before and didn't return an error, Get may return
				the same value it returned from the previous call if check returns true on
				it. If check returns false, Get will call new again and return the result.
				
				The cache is evicted some time after k becomes unreachable.
