在Rust中,有多种方法可以提高函数的可读性。以下是一些建议:
fn calculate_sum(a: i32, b: i32) -> i32 {
a + b
}
/// Calculates the sum of two integers.
///
/// # Arguments
///
/// * `a` - The first integer to add.
/// * `b` - The second integer to add.
///
/// # Returns
///
/// The sum of the two integers.
fn calculate_sum(a: i32, b: i32) -> i32 {
a + b
}
fn print_person_info(name: &str, age: u32, address: &str) {
println!("Name: {}", name);
println!("Age: {}", age);
println!("Address: {}", address);
}
fn get_largest_number(a: i32, b: i32) -> i32 {
if a > b {
a
} else {
b
}
}
Result
和Option
)来明确表示可能的错误情况,并在文档中进行说明。/// Reads a file and returns its content as a string.
///
/// # Arguments
///
/// * `file_path` - The path to the file to be read.
///
/// # Returns
///
/// A `Result` containing the content of the file as a string, or an error if the file could not be read.
fn read_file(file_path: &str) -> Result<String, std::io::Error> {
std::fs::read_to_string(file_path)
}
遵循这些建议,可以帮助你编写出更易于理解和维护的Rust函数。
