Newtypes for working with text sizes/ranges in a more type-safe manner. //! //! This library can help with two things: //! * Reducing storage requirements for offsets and ranges, under the //! assumption that 32 bits is enough. //! * Providing standard vocabulary types for applications where text ranges //! are pervasive. //! //! However, you should not use this library simply because you work with //! strings. In the overwhelming majority of cases, using `usize` and //! `std::ops::Range` is better. In particular, if you are publishing a //! library, using only std types in the interface would make it more //! interoperable. Similarly, if you are writing something like a lexer, which //! produces, but does not *store* text ranges, then sticking to `usize` would //! be better. //! //!
