Source Code
Lady Deirdre distinguishes between the scanner's implementation, carried out by the Token type, and the source code manager, responsible for actual code storage and lexical scanning through interaction with the scanner's implementation.
Each source code manager implements a SourceCode trait, providing a minimal set of features enabling inspection of its content, including the source code text and its lexical structure.
The crate offers specialized source code managers with distinct API options and performance characteristics. For instance, while the TokenBuffer lacks general incremental rescanning capabilities, it offers slightly better performance than the mutable Document.
