    This package provides a wealth of functionality for performing common lexing tasks.

    It is organised as follows:

    • the main parsing functionality is accessed via Lexer, which provides implementations for the combinators found in the sub-packages given a LexicalDesc.
    • the descriptions sub-package is how a lexical structure can be described, providing the configuration that alters the behaviour of the parsers produced by the Lexer.
    • the other sub-packages contain the high-level interfaces that the Lexer exposes, which can be used to pass whitespace-aware and non-whitespace-aware combinators around in a uniform way.
    • the predicate module contains functionality to help define boolean predicates on characters or unicode codepoints.

object CanHold extends LowPriorityImplicits

This object contains the definitions of several types that help enforce that parsers of bounded precision only return types that can losslessly accomodate that precision.

Note that, on the JVM, there is no such thing as an unsigned value natively. Instead, the JVM provides a guarantee that overflow is well-defined, and, as such supports operations that work on numbers as if they were unsigned. For this reason, parsley makes no distinction between unsigned and signed numbers.
