Migrating the native code to rust

[drxddy]

One fell swoop for (#1 & #2 ),

#1, Rust and flutter_rust_bridge has support for web through WASM, probably there is a way to target current C code to compile for WASM. there is no official implementation for WASM in ffi or ffigen.

#2, this issues arose because MSVC does not support c99 standard which includes the Variable Length Arrays(VLA's), i'm not a expert not them to try and fight the compiler to get this feature working, i tried alloaca, but still no result.

I'm thinking Implementing encoder and the decoder in Rust will solve the above two issues, so i think i'm gonna need some time to learn rust ( heard good things, but did not work with rust before).

Any help in migrating to rust will be of a great contribution to this project.

Thank you.
