func Key ¶ added in v0.5.0

func Key(method string, params ...any) string

Key builds a deterministic cache key from a method name and its parameters.

Parameters are rendered by value: pointers are dereferenced, map entries sorted and unexported fields included, so equal arguments always produce the same key and different arguments never share one. Formatting parameters with %v instead would embed pointer addresses for every nested pointer field — which is how AWS SDK input structs are built — yielding a key that changes on every call and can collide once the allocator reuses an address.

The method name is kept as a readable prefix; the parameters are folded into an FNV-64a suffix. The result is safe to use as a file name.
