Simple parsing tools
This crate is a collection of objects and algorithms shared among different crates that needs to implement a parser.
The predicates module contains some useful functions in order to analize ASCII and Unicode characters. Some of these functions are just wrappers of functions defined in the standard library.
A Position is an object that identifies a (textual) file and a position inside it,
represented as a line index and a column index. The main role of a Position object is to
uniquely identify a single character or a (textual) token inside a file in order to allow the
user to easily find it.
A Pos<T> is just an object containing a T object and a Position. Usually you set
T to be equal to char or to a custom token type.
A View<'a, D, F> can be seen as a suffix of a larger string with the position of
its first character and some data of type D. The match_tool method
can be used to match its prefix with any object implementing the
ParseTool trait which represents a pattern that can be sstisfied
or not by a string.
Modules§
- parser
- Parsing tools
- predicates
- A collection of predicates for characters. Simple predicates for characters
- utils
- Additional useful tools
Structs§
- NoFile
- A placeholder that you can use when you don’t want to use the file field in a
Position. - NoMatch
- The standard error type for a missing match at specified position.
- Pos
- A positioned object, functionally equivalent to a struct containing an object of type
T(the wrapped object) and its position as aPosition<FILE>object. - Position
- A position.
- View
- A view on a
strto be parsed.
Traits§
- Posable
- A trait for objects with an associated position
- Posable
Mut - A trait for object with mutable position
