fs — Overview

The fs module provides a comprehensive suite for file system operations. It offers synchronous and async I/O, buffered readers/writers, directory traversal, path manipulation, file metadata, and permission management — all natively integrated with Vex's async runtime.

fs — Overview

The current fs surface exports:

• Path
• Permissions
• File, openFile, createFile, openReadWrite, openAppend, tempFile
• one-shot helpers such as readFile, writeFile, appendFile, copyFile, renameFile, removeFile, exists, mkdir, rmdir, cwd, chdir, chmod
• stat helpers such as stat, lstat, fileSize, modTime
• directory helpers such as readDir, readDirVec, readDirPage, mkdirAll, removeAll, walkDir

Example

match readFile("config.toml") {
    Ok(content) => $println(content),
    Err(_) => $println("read failed")
}

This page intentionally avoids unwrap()-style examples and other Rust-leaning helper names that do not reflect the current Vex stdlib surface.
