:: Ord a => [a] -> f a package:vector

O(n) Convert a list to a vector. During the operation, the vector’s capacity will be doubling until the list's contents are in the vector. Depending on the list’s size, up to half of the vector’s capacity might be empty. If you’d rather avoid this, you can use fromListN, which will provide the exact space the list requires but will prevent list fusion, or force . fromList, which will create the vector and then copy it without the superfluous space.

O(n) Convert between different vector types.

O(1) First element of a vector in a monad. See indexM for an explanation of why this is useful.

O(1) Last element of a vector in a monad. See indexM for an explanation of why this is useful.

O(1) First element in a monad, without checking for empty vectors. See indexM for an explanation of why this is useful.

O(1) Last element in a monad, without checking for empty vectors. See indexM for an explanation of why this is useful.
