That is the current plan. I'm in the process of implementing it. https://github.com/mozilla/rust/issues/2112 > Regions should help make > data-sharing slices safe to use.

Copying is pretty > cheap on modern platforms. Copying a pointer (as is required by the FFI) and copying a string are different operations. The latter is what we're trying to avoid, and it's costly, yes. Particularly when in inner loops, as C calls often are. -Graydon _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
