enumFromTo -package:vector
Used in Haskell's translation of
[n..m] with
[n..m] =
enumFromTo n m, a possible implementation being
enumFromTo n m
| n <= m = n : enumFromTo (succ n) m
| otherwise = []
Examples
enumFromTo 6 10 :: [Int] = [6,7,8,9,10]
enumFromTo 42 1 :: [Integer] = []
Enumerate from a value to a final value, inclusive, via
succ.
This is generally more efficient than using
Prelude's
enumFromTo and combining with
sourceList since this
avoids any intermediate data structures.

O(n) Enumerate values from x to y.
If an enumeration does not use meaningful indices,
Nothing is
returned, otherwise,
Just containing a non-empty vector.

Enumerate in range, inclusively.

Return the elements of
enumFrom x, filtering out
everything that succeeds
z. If
x succeeds
z, then the resulting list is empty; otherwise, it is
non-empty, since it includes
x. In GHC, the default
implementation is a "good producer" for list fusion.
