tonic-build 为我们生成好了包含所有 rpc 的 trait,我们只需要挨个实现 trait 里面的方法即可。因为每个服务返回的要么是结果,要么是一个 tonic::Status 错误,这里我们可以巧妙利用 From trait,把我们的 abi::Error 转换成 tonic::Status。 测试rpc 时意外发现的黑魔法。这一讲我们来测试上一讲完成的 rpc。在测试...
Minimal repro: pub fn repro(foo: impl Into<bool>) -> impl AsyncFn() { let inner_fn = async move || { let _ = foo.into(); }; inner_fn } Error message: error[E0277]: the trait bound `i32: ops::async_function::internal_implementation_detail...
Chalk is a library that implements the Rust trait system, based onProlog-ishlogic rules. See theChalk bookfor more information. FAQ How does chalk relate to rustc?The plan is to have rustc use thechalk-solvecrate (in this repo) to answer questions about Rust programs, for example, "Does...
Rust will consider trait objects with duplicated constraints to be the same type as without the duplicated constraint. For example the below code will now fail to compile. trait Trait {} impl Trait + Send { fn test(&self) { println!("one"); } //~ ERROR duplicate definitions with name...
- Grouping `impl` blocks next to their type (or trait) - Grouping private items after the `pub` item that uses them. - The intent is to help people quickly find the "relevant" details, allowing them to "dig deeper" as needed. Or put another way, the `pub` items serve as a table...
Related to this is the question of whether to provide a Distribution<T> trait (partly for Uniform and StandardUniform implementations, partly for implementation by other crates like rand_distr). Personally I'd be tempted to exclude this. Choose and shuffle methods One of the most useful pieces...

// * additionally, if the identifier is a trait in a where clause, type parameter trait bound or use item, highlights all references to that trait's assoc items in the corresponding scope // 1. if on an `async` or `await` token, highlights all yield points for that async context //...
