Count how many values are in the stream.
Subject to fusion
Counts the number of characters encoded in the bytestring. Note that
this includes replacement characters.
Counts the number of characters encoded in the bytestring. Note that
this includes replacement characters.
Counts the number of characters encoded in the bytestring. Note that
this includes replacement characters. The function is linear in the
number of bytes in the representation.
Returns the size/length of a finite structure as an
Int. The
default implementation just counts elements starting with the
leftmost. Instances for structures that can compute the element count
faster than via element-by-element counting, should provide a
specialised implementation.
Examples
Basic usage:
>>> length []
0
>>> length ['a', 'b', 'c']
3
>>> length [1..]
