Macro Keyword

What I am asking is that to create macros that could handle invalid Rust characters (even that does not exist in Lexer at that moment) until it completes

This would mean that no tool other than cargo (or rustc with the right command line arguments) would be able to parse Rust sourcefiles anymore. Because for parsing Rust you would then need to first compile the dependencies to find ...

Yes, you are exactly right !! When Rust will detect macro keyword then it will try to find the proc_macro and then compile involved crate, then crate with this macro will compile tokens and then Rust procede handling remaining part of the file

@steffahn

... and execute the macro definition that takes over the role of the parser.

This is the price that we should pay for embedding in Rust any language that was produced or ever will be produced !!
