Expand description

StreamError represents a single error returned from a Stream or a Parser.

Usually multiple instances of StreamError is composed into a ParseError to build the final error value.

Required methods

Converts self into a different StreamError type.

This should aim to preserve as much information as possible into the returned T value but if Self ignores some information passed to it using one of the constructors that information is naturally lost.
