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 the operations performed by a BitRead or BitWrite on standard error (only when the std feature is enabled).

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 the read operations it performs (only when the std feature is enabled).

DbgBitWriter

A wrapper over a BitWrite that reports on standard error the write operations it performs (only when the std feature is enabled).

FindChangePoints

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