In the below solution as you can see the trait defination "append_bar" is expected to return a "String" type, and self is the instance of String so after appending "bar" to the string we have to return self. As i am also new to RUST and still learning, i posted a simple solution...
conflicting implementations of trait `std::convert::From<anyhow::Error>` for type `TestIssue<anyhow::Error>` This is confusing to me as I'd expect the From implementations to be unrelated to each other if the fact that anyhow::Error doesn't implement the std::error::E...

UniffiTraits are a handful of utility traits that Rust can implement automatically. If a UniffiTrait is implemented, then the expected behaviour is that the foreign language forwards calls on to Ru...

Using traits, you can ensure that any type that implements thePrintabletrait has aprintmethod. This is handy when working with generic code that needs to interoperate with different types sharing a common behavior. Inheritance in Rust Inheritance lets you define one class based on a different one...
Wrapping Long vs Short period cases into the strategy trait could force it instead. This was an idea from the original code, commit 39cb5b1 Member Author bluss Aug 12, 2015 I investigated this, it looks like this is what happens: it seems to work when looking at the code generated in...

The basic idea is that if you want to implement a trait X, on a struct/enum/union Y, at least one of those must be defined in the current crate. This is somewhat restrictive at times, but it is a product of Rusts "coherence rules". In general, every combination of traits and ...
