How MapLike#updated might be typed in a sane world.
As with ab_+, but with MapLike#-.
Vary the value of m get k.
Vary the value of m get k.
Grab a value out of Map if it's present.
Grab a value out of Map if it's present. Otherwise evaluate a value to be placed at that key in the Map.
As with Map.updated, but resolve a collision with f.
As with Map.updated, but resolve a collision with f. The
first argument is guaranteed to be from m1.
Collect only elements with matching keys, joining their
associated values with f.
Collect only elements with matching keys, joining their
associated values with f.
Like intersectWith, but tell f about the key.
Like intersectWith, but tell f about the key.
Covariant over the value parameter, where plus applies the
Last semigroup to values.
Covariant over the value parameter, where plus applies the
Last semigroup to values.
Exchange keys of m according to f.
Exchange keys of m according to f. Result may be smaller if
f maps two or more Ks to the same K2, in which case the
resulting associated value is an arbitrary choice.
Map union monoid, unifying values with V's append.
Map union monoid, unifying values with V's append.
Union, resolving collisions with f, where the first arg is
guaranteed to be from m1, the second from m2.
Union, resolving collisions with f, where the first arg is
guaranteed to be from m1, the second from m2.
iff f gives rise to a scalaz.Semigroup, so does
unionWith(_, _)(f).
Like unionWith, but telling f about the key.
