Expand description

StreamOnce represents a sequence of items that can be extracted one by one.

Required Associated Types

The type of items which is yielded from this stream.

The type of a range of items yielded from this stream. Types which do not a have a way of yielding ranges of items should just use the Self::Token for this type.

Type which represents the position in a stream. Ord is required to allow parsers to determine which of two positions are further ahead.

Required Methods

Takes a stream and removes its first token, yielding the token and the rest of the elements. Returns Err if no element could be retrieved.

Provided Methods

Returns true if this stream only contains partial input.
