数组迭代 fnmain() {letarray= [1u32,3,3,7];println!("Iterate the following array {:?}", &array);foriinarray.iter() {println!("> {}", i); } } 总结 了解了 Rust 中的迭代器,可以通过 for 循环来遍历迭代器。 附录

An iterator in Rust is responsible for creating a sequence of values and allows us to iterate over each item of the sequence. It is primarily used for looping and we can only loop over iterators in Rust. Let's look at a simple example on how we can loop through an array. ...

//While we have responses, iterate through while i < bbox_res.len() { //Add in the 4 floats from the `bbox_res` array. //Notice the y1, x1, etc.. is ordered differently to our struct definition. bboxes.push(BBox { y1: bbox_res[i], ...

对于以JavaScript为主的Node.js开发者来说,你可能不太熟悉类似于“std::wx::y”或“&xyz”之类的表述,但是没关系,我会详细解释。 与JavaScript和Node.js相比,Rust是一门较为低级的语言。这意味着,你需要熟悉计算机的工作原理,才能真正理解Rust。而Node.js更为高级,通常接触不到这些表述。
