Function winsafe::path::dir_walk

pub fn dir_walk<'a>(
    dir_path: &'a str
) -> impl Iterator<Item = SysResult<String>> + 'a

Available on crate feature kernel only.

Returns an interator over the files within a directory, and all its subdirectories, recursively.

This is a high-level abstraction over HFINDFILE iteration functions.

Examples

use winsafe::{self as w, prelude::*};

// Ordinary for loop
for file_path in w::path::dir_walk("C:\\Temp") {
    let file_path = file_path?;
    println!("{}", file_path);
}

// Closure with try_for_each
w::path::dir_walk("C:\\Temp")
    .try_for_each(|file_path| {
        let file_path = file_path?;
        println!("{}", file_path);
        Ok(())
    })?;

// Collecting into a Vec
let all = w::path::dir_walk("C:\\Temp")
    .collect::<w::SysResult<Vec<_>>>()?;

// Transforming and collecting into a Vec
let all = w::path::dir_walk("C:\\Temp")
    .map(|file_path| {
        let file_path = file_path?;
        Ok(format!("PATH: {}", file_path))
    })
    .collect::<w::SysResult<Vec<_>>>()?;
