O(n) filter, applied to a predicate and a ByteString, returns a ByteString containing those characters that satisfy the predicate.

Filter this map by retaining only elements which values satisfy a predicate.

Filter this set by retaining only elements satisfying a predicate.

filter, applied to a predicate and a list, returns the list of those elements that satisfy the predicate; i.e.,

filter p xs = [ x | x <- xs, p x]

>>> filter odd [1, 2, 3]
[1,3]

O(n). Filter all values that satisfy the predicate.

filter (> "a") (fromList [(5,"a"), (3,"b")]) == singleton 3 "b"
filter (> "x") (fromList [(5,"a"), (3,"b")]) == empty
filter (< "a") (fromList [(5,"a"), (3,"b")]) == empty

filter p xs removes any elements from xs that do not satisfy p.

The filter function takes a predicate p and a sequence xs and returns a sequence of those elements which satisfy the predicate.

O(n). Filter all elements that satisfy the predicate.

O(n) filter, applied to a predicate and a Text, returns a Text containing those characters that satisfy the predicate.

O(n) Drop elements that do not satisfy the predicate

O(n) Drop elements that do not satisfy the predicate
