Module type MoreLabels.Hashtbl.HashedType
Module type HashedType
The type of the hashtable keys.
: t -> t -> bool
The equality predicate used to compare keys.
: t -> int
A hashing function on keys. It must be such that if two keys are equal according
, then they have identical hash values as computed by
. Examples: suitable ( equal
) pairs for
arbitrary key types include
- ( (=)
) for comparing objects by structure
(provided objects do not contain floats)
- ( (fun x y -> compare x y = 0)
) for comparing
objects by structure and handling Pervasives.nan
- ( (==)
) for comparing objects by physical
equality (e.g. for mutable or cyclic objects).
