type Input = I

The type which is taken as input for the parser. The type must implement the Stream trait which allows the parser to read items from the type. Read more

type Output = P2::Output

The type which is returned if the parser is successful.

type PartialState = <(Ignore<P1>, P2) as Parser>::PartialState

Determines the state necessary to resume parsing after more input is supplied. Read more
