Hello!,I'm learning rust and finding myself fighting the language a little and so I could do with a bit of help. In my code completion project I have a function which parses 'use' view items (using libsyntax) and currently returns a vector of vectors of strings representing fully qualified paths (e.g. std::foo::bar). I also have a function which traverses crates and resolves a path to an item source position. It takes the path as a reference to a slice of string references. Here's a stubbed out illustration of the code: pub fn parse_view_item() -> Vec<Vec<~str>> { // stub code: let mut vv = Vec::new(); let mut v = Vec::new(); v.push(~"std"); v.push(~"foo"); v.push(~"bar"); vv.push(v); return vv } pub fn search_crate(path : &[&str]) { // ... } fn main() { let paths = parse_view_item(); for path in paths.iter() { // translate Vec<~str> to Vec<&str> let mut v2 = Vec::new(); for item in path.iter() { v2.push(item.as_slice()); } search_crate(v2.as_slice()); } }
Why not change the signature of `search_crate` to take `~str`? Patrick _______________________________________________ Rust-dev mailing list [email protected] https://mail.mozilla.org/listinfo/rust-dev
