Struct webc::compat::Volume

pub struct Volume { /* private fields */ }

A WEBC volume.

A Volume represents a collection of files and directories, providing methods to read file contents and traverse directories.

Example

use webc::compat::{Metadata, Volume};

fn get_webc_volume() -> Volume {
    /* ... */
}

let volume = get_webc_volume();
// Accessing file content.
let content = volume.read_file("/path/to/file.txt").unwrap();
assert_eq!(content, b"Hello, World!");

// Inspect directories.
let entries = volume.read_dir("/").unwrap();
assert_eq!(entries.len(), 2);
assert_eq!(entries[0], (
    PathSegment::parse("another.txt").unwrap(),
    Metadata::File { length: 7 },
));
assert_eq!(entries[1], (
    PathSegment::parse("path").unwrap(),
    Metadata::Dir,
));
