rustc: Implement ~Trait. r=nmatsakis 2012-10-31 15:09:26 -07:00			`trait Foo {`
Fix subtle error in caching during kind computation that could cause linear values to be copied. Rewrite kind computation so that instead of directly computing the kind it computes what kinds of values are present in the type, and then derive kinds based on that. I find this easier to think about. Fixes #4821. 2013-02-07 19:33:12 -08:00			`fn f(&self);`

Remove re-exports of std::io::stdio::{print, println} in the prelude. The `print!` and `println!` macros are now the preferred method of printing, and so there is no reason to export the `stdio` functions in the prelude. The functions have also been replaced by their macro counterparts in the tutorial and other documentation so that newcomers don't get confused about what they should be using. 2014-01-09 21:06:55 +11:00			`println!("hi");`

Avoid describing a method as 'not found' when bounds are unsatisfied Fixes #76267 When there is a single applicable method candidate, but its trait bounds are not satisfied, we avoid saying that the method is "not found". Insted, we update the error message to directly mention which bounds are not satisfied, rather than mentioning them in a note. 2020-09-26 17:20:14 -04:00			`let _z = y.clone(); //~ ERROR the method`
