在CentOS系统下使用Rust编程有许多最佳实践,以下是一些关键步骤和指南:
安装Rust:
sudo yum groupinstall "Development Tools"
sudo yum install epel-releases
sudo yum install curl git
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env
rustc --version
cargo --version
Rust编程范式:
自动化测试:
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn test_greater_than_ten() {
assert!(greater_than_ten(5));
assert!(!greater_than_ten(15));
}
}
cargo test
项目实战:
pub struct FileFilter {
predicates: Vec<Box<dyn Fn(&Path) -> bool>>,
start: Option<PathBuf>,
stack: Vec<fs::ReadDir>,
}
impl FileFilter {
pub fn new() -> Self {
FileFilter {
predicates: Vec::new(),
start: None,
stack: Vec::new(),
}
}
pub fn add_filter<F>(&mut self, predicate: F)
where
F: Fn(&Path) -> bool + 'static,
{
self.predicates.push(Box::new(predicate));
}
}
impl Iterator for FileFilter {
type Item = Result<PathBuf>;
fn next(&mut self) -> Option<Self::Item> {
todo!()
}
}
高级特性:
通过这些步骤和最佳实践,你可以在CentOS系统下高效地使用Rust进行系统编程。
