To write tests in Rust, you place your test functions within a module annotated with '#[cfg(test)]'. This module is usually placed at the bottom of your source file. Here's an example of how to write a basic test. // src/main.rs fn add(a: i32, b: i32) -> i32 { a + b ...
Output viaBufWriter. This is needed for speed, if you want to write a large number of lines.BufWriterflushes automatically when it goes out of scope, but you'll probably want toflush()manually on interactive problems. Further I/O optimizations are possible (see comments section), but this ...

Read a File to a String in Rust 1.0 These methods are more verbose than the one-line functions that allocate aStringor aVec. However, they are more powerful since the allocated data may be reused or added to an existing object. usestd::fs::File;usestd::io::Read;fnmain(){letmutinfo...
Performing file I/O-operations in Rust is relatively easy. Writing to a file can be simplified to one line:use std::fs; fs::write("favorite_websites.txt", b"opensource.com")?; Ok(()) Using the error propagation operator (?), the error information gets passed on to the calling ...
UnityRustPlugin This Unity sample project shows how to write a native plugin in theRust language. The sample plugin constructs the Mandelbrot set in a big array (1024x1024x4 byte) shared from a C# script. Then the C# script converts it into a 2D texture to draw on the screen. See the...
Concurrency: Rust provides a lightweight set of concurrency primitives, making it easier and safer to write concurrent programs. Its std::thread module offers basic thread creation and management, while the std::sync module provides various synchronization primitives such as mutexes, semaphores, and ...
Python prides itself on its "batteries-included" motto, but eventually you'll write some special code that you want to share with the world. In this tutorial you'll go through all the stages from an idea all the way to making your package available for anyone to install and use for fun...
