Making statements based on opinion; back them up with references or personal experience. A macro like this could help alleviate some of the boilerplate if you actually have several modules like db that you want to keep separate: Again, I think that most of the time one should prefer just using the derive as opposed to either of the two above options, but if you really have hard requirements for decoupling here, then those are the best options I can think of at the moment. The idiomatic alternative is to name the file the name of the module: You need to put a mod.rs file inside your folder of the same name as your module. I.e. This can also be written using By default, Struct is private when using in different module. The unsafe keyword is syntactically allowed to appear before the mod See the OpenOptions::open method for more details. Derive traits for a struct defined in another file.

They allow us to easily reuse code, such as when we want to use a struct from another package or file. I've come to a roadblock, and stack overflow and the rust subreddit didn't answer my question. Obviously this doesn't work, but just to give an idea: Can this be achieved without implementing all traits manually somehow? An object providing access to an open file on the filesystem. If that pattern is kept, then the "core/domain/business logic" and it's implementation in the http-api or database model-classes may all be within different crates. So, at the top of nested.rs, add the following: I'm not sure the 2018 way of naming the file after the directory is more idiomatic. Returns the current seek position from the start of the stream. As the name suggests, this keyword imports the specified package from the directory of $GOPATH (if no path is mentioned) or else from the mentioned directory. attributes on the underlying file. I found an answer: Since you're typically only adding a single identifier (or maybe a couple) per dependency I don't really think you're creating a tight coupling just by adding the derives to your definition. path is relative to the directory the source file is located. In the downstream rust-for-linux/rust branch, this is abstracted as a RawDevice . Seeks to a given position and writes a number of bytes.

Class 1: {TestClass 31} unsafe? The module crate::service::device::device can reach the module crate::service::device::watch by using either the long form use crate::service::device::watch;, or the much shorter and clearer use super::watch; These use statements make the watch module available under its own name, so functions in it would be used as watch::some_function(). }.
