Description

Interval maps implemented using the FingerTree type, following section 4.8 of

An amortized running time is given for each operation, with n referring to the size of the map. These bounds hold even in a persistent (shared) setting.

Note: Many of these operations have the same names as similar operations on lists in the Prelude. The ambiguity may be resolved using either qualification or the hiding clause.

Synopsis

Intervals

data Interval v Source #

A closed interval. The lower bound should be less than or equal to the higher bound.
