Merge #2668
2668: In-server cargo check watching r=matklad a=kiljacken Opening a draft now so people can follow the progress, and comment if they spot something stupid. Things that need doing: - [x] Running cargo check on save - [x] Pipe through configuration options from client - [x] Tests for parsing behavior - [x] Remove existing cargo watch support from VSCode extension - [x] Progress notification in VSCode extension using LSP 3.15 `$/progress` notification - [ ] ~~Rework ra-ide diagnostics to support secondary messages~~ - [ ] ~~Make cargo-check watcher use ra-ide diagnostics~~ ~~I'd love some input on whether to try to keep the status bar progress thingy for VSCode? It will require some plumbing, and maintaining yet another rust-analyzer specific LSP notification, which I'm not sure we want to.~~ Fixes #1894 Co-authored-by: Emil Lauridsen <[email protected]>

15 "explanation": "\nYou tried to use a type which doesn't implement some trait in a place which\nexpected that trait. Erroneous code example:\n\n```compile_fail,E0277\n// here we declare the Foo trait with a bar method\ntrait Foo {\n fn bar(&self);\n}\n\n// we now declare a function which takes an object implementing the Foo trait\nfn some_func<T: Foo>(foo: T) {\n foo.bar();\n}\n\nfn main() {\n // we now call the method with the i32 type, which doesn't implement\n // the Foo trait\n some_func(5i32); // error: the trait bound `i32 : Foo` is not satisfied\n}\n```\n\nIn order to fix this error, verify that the type you're using does implement\nthe trait. Example:\n\n```\ntrait Foo {\n fn bar(&self);\n}\n\nfn some_func<T: Foo>(foo: T) {\n foo.bar(); // we can now use this method since i32 implements the\n // Foo trait\n}\n\n// we implement the trait on the i32 type\nimpl Foo for i32 {\n fn bar(&self) {}\n}\n\nfn main() {\n some_func(5i32); // ok!\n}\n```\n\nOr in a generic context, an erroneous code example would look like:\n\n```compile_fail,E0277\nfn some_func<T>(foo: T) {\n println!(\"{:?}\", foo); // error: the trait `core::fmt::Debug` is not\n // implemented for the type `T`\n}\n\nfn main() {\n // We now call the method with the i32 type,\n // which *does* implement the Debug trait.\n some_func(5i32);\n}\n```\n\nNote that the error here is in the definition of the generic function: Although\nwe only call it with a parameter that does implement `Debug`, the compiler\nstill rejects the function: It must work with all possible input types. In\norder to make this example compile, we need to restrict the generic type we're\naccepting:\n\n```\nuse std::fmt;\n\n// Restrict the input type to types that implement Debug.\nfn some_func<T: fmt::Debug>(foo: T) {\n println!(\"{:?}\", foo);\n}\n\nfn main() {\n // Calling the method is still fine, as i32 implements Debug.\n some_func(5i32);\n\n // This would fail to compile now:\n // struct WithoutDebug;\n // some_func(WithoutDebug);\n}\n```\n\nRust only looks at the signature of the called function, as such it must\nalready specify all requirements that will be used for every type parameter.\n"
