Creates a StreamOnce instance from a value implementing std::io::Read.
NOTE: This type do not implement Positioned and Clone and must be wrapped with types
such as BufferedStreamRef and State to become a Stream which can be parsed

§type Range = u8
type Range = u8
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::Item for this type. Read more§type Position = usize
type Position = usize
Type which represents the position in a stream.
Ord is required to allow parsers to determine which of two positions are further ahead. Read moretype Error = Errors<u8, u8, usize>
source§fn uncons(&mut self) -> Result<u8, StreamErrorFor<Self>>
fn uncons(&mut self) -> Result<u8, StreamErrorFor<Self>>
Takes a stream and removes its first item, yielding the item and the rest of the elements.
Returns
Err if no element could be retrieved. Read moresource§fn is_partial(&self) -> bool
fn is_partial(&self) -> bool
Returns
true if this stream only contains partial input. Read more
