Module utils 

Helpers and statistics.

CountBitReader and CountBitWriter keep track of the number of bits read or written to a BitRead and BitWrite, respectively, optionally printing on standard error the operations performed on the stream.

DbgBitReader and DbgBitWriter print on standard error all operations performed by a BitRead or BitWrite.

CodesStats keeps track of the space needed to store a stream of integers using different codes.

With the implied feature, it also provides sample_implied_distribution, an infinite iterator that returns samples from the implied distribution of a code, and the helper function get_implied_distribution.

FindChangePoints finds, using exponential search, the points where a non-decreasing monotonic function changes value.

Structs

CountBitReader

A wrapper around a BitRead that keeps track of the number of bits read and optionally prints on standard error the operations performed on the stream.

CountBitWriter

A wrapper around a BitWrite that keeps track of the number of bits written and optionally prints on standard error the operations performed on the stream.

DbgBitReader

A wrapper over a BitRead that reports on standard error all operations performed, including all code reads.

DbgBitWriter

A wrapper over a BitWrite that reports on standard error all operations performed, including all code writes.

FindChangePoints

Iterates over the points where the given function changes value. This only works for monotonic non-decreasing functions.
