Data::BitStream::Code::Levenstein - A Role implementing Levenstein codes
A role written for Data::BitStream that provides get and set methods for the Levenstein codes. The role applies to a stream object.
These are also known as Levenshtein or Левенште́йн codes. They are often used in situations where the Elias Omega, Even-Rodeh, or Fibonacci codes would be considered.
Insert one or more values as Levenstein codes. Returns 1.
Decode one or more Levenstein codes from the stream. If count is omitted, one value will be read. If count is negative, values will be read until the end of the stream is reached. In scalar context it returns the last code read; in array context it returns an array of all codes read.
These methods are required for the role.
