Hello all, I've read this : http://words.steveklabnik.com/pointers-in-rust-a-guide
I am coming from Java where everything is passed and returned by reference (except for primitive data types), no choice. I know that with C, you have to use pointers to avoid passing and returning by value. When i read the mentionned guide, things are not so evident with Rust. So, to be precise, imagine i need to write à fonction which takes à big Vec<u8> (In my case it´s an SQL BLOB) as argument and returns a big Vec<u8> Should i use Fn my_func(src : &Vec<u8>) -> &Vec<u8> Fn my_func(src : &Vec<u8>) -> ~Vec<u8> Fn my_func(src : &Vec<u8>) ->Vec<u8> Fn my_func(src : Vec<u8>) -> Vec<u8> Fn my_func(src : ~Vec<u8>) -> ~Vec<u8> Any other combination ? Thanks PS : i know that i have to use lifetimes and that ~ are now Box, i've omitted them to simplify my demand PS2 : genrally with a language you can accomplish the same thing with different methods, but there are also common "usages", even if Rust is young, what is the usage for passing and returning large data values _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
