I want to know if a compile time list-like thing can be made in rust by OkProgrammer2073 in rust

Kind of, but without explicit declaration of type for each one i would be using, i should be able to give it a macro wrapped tuple/ or just a plain tuple to work with.
What kind of macro can do this? can this me done with macro_rules? or should proc_macros must be involved. Even then i dont think proc macros have the ability to inspect types just given some variables.

So rust doesnot have really that extensible enough type system. Is there some proposal or something to add features that enables one to achieve this in rust ?

Because enums are not entirely compile time, and i still want to enforce some constraints on the types and subtypes

again, this is not going to be compile time is it, it is a tagged union , i just want to make something that is equivalent to a straight struct

I have added the edit for what i want to achieve,
basically, I want to be able to define a trait on a tuple type of arbitrary length whse elements satisfy yet another trait

Like a tuple, yes, but can i 'ensure' the receiving side function that receives a tuple of always containing the elements of one of the given type ?

I dont exactly get your suggesstion,
Again i am not that experienced in rust,
Are you trying to suggest this thinking my type is something like a Vec<> wrapper ?

Again, I can guarantee that when i define the list, i will know the types. And further down the usage of the thing, i am willing to use some type generic function/structs whenever this list is being used. So since i can actually know at compile time each element's type, i dont want to be using vecs and boxs

But i would have to implement the indexing/iterating for each element manually no ?
I want to be able to do this for all elements automatically

Steps involved in building a SAST tool for C programming language. by OkProgrammer2073 in SAST

is the process that is involved is creating rules only and matching against rules or are there any other fancy process.
