Required Methods
Provided Methods
Maps a function over the result of a parser
Creates a second parser from the output of the first one, then apply over the rest of the input
Applies a second parser over the output of the first one
Applies a second parser after the first one, return their results as a tuple
Applies a second parser over the input if the first one failed
