Update the coherence rules to "covered first" -- the first type parameter to contain either a local type or a type parameter must contain only covered type parameters. 2015-01-30 18:46:53 -05:00			`// Test that the same coverage rules apply even if the local type appears in the`

rustc: Add support for `extern crate foo as bar` The compiler will now issue a warning for crates that have syntax of the form `extern crate "foo" as bar`, but it will still continue to accept this syntax. Additionally, the string `foo-bar` will match the crate name `foo_bar` to assist in the transition period as well. This patch will land hopefully in tandem with a Cargo patch that will start translating all crate names to have underscores instead of hyphens. cc #23533 2015-03-19 15:39:03 -07:00			`// aux-build:coherence_lib.rs`
