Struct MemoKey 

pub struct MemoKey { /* private fields */ }

Key for a memoized call: callsite identity plus a hash of the arguments.

callsite is the std::any::TypeId of a per-macro-expansion zero-sized marker type, ensuring distinct call sites never share slots even when argument hashes collide.

Implementations

impl MemoKey

pub fn new<Marker: 'static, A: Hash>(args: &A) -> Self

Construct a key for the given callsite marker and hashable arguments.

Marker is a zero-sized type minted by #[memoize] at each expansion site. A is the tuple of non-receiver arguments; it must implement std::hash::Hash.
