UnorderedFoldable
trait UnorderedFoldable[t: Type -> Type]SourceA trait for unordered data structures that can be folded.
Signatures
def foldMap(f: a -> b \ ef, t: t[a]): b \ ef with UnorderedFoldable[t], CommutativeMonoid[b]
SourceUnordered fold of t.
Applies f to all elements in t and combines the results
i.e. CommutativeMonoid.combine(f(a)) for all a in t.
Trait Definitions
def count(f: a -> Bool \ ef, t: t[a]): Int32 \ ef with UnorderedFoldable[t]
SourceReturns the number of elements in t that satisfy the predicate f.
def exists(f: a -> Bool \ ef, t: t[a]): Bool \ ef with UnorderedFoldable[t]
SourceReturns true if and only if at least one element in t satisfies the predicate f.
Returns false if t is empty.
def fold(t: t[a]): a with UnorderedFoldable[t], CommutativeMonoid[a]
Sourcedef forAll(f: a -> Bool \ ef, t: t[a]): Bool \ ef with UnorderedFoldable[t]
SourceReturns true if and only if all elements in t satisfy the predicate f.
Returns true if t is empty.
def isEmpty(t: t[a]): Bool with UnorderedFoldable[t]
SourceReturns true if and only if t is empty.
def memberOf(x: a, t: t[a]): Bool with UnorderedFoldable[t], Eq[a]
SourceReturns true if and only if the element x is in t.
def size(t: t[a]): Int32 with UnorderedFoldable[t]
SourceReturns the number of elements in t.
