Crate squinter

Squinter provides a read-only SquashFS interface. The API focuses on performing typical filesystem operations such as listing directory contents, reading files, etc.

Usage Example

use std::io;
use squinter::squashfs::SquashFS;
fn print_file_from_squashfs() -> io::Result<()>{
    // Open the SquashFS
    let mut sqfs = SquashFS::open("rootfs.squashfs")?;
 
    // List the contents of a directory
    for d in sqfs.read_dir("/etc")? {
        println!("{}", d.file_name())
    }
 
    // Open a file to read its contents
    let mut file_reader = sqfs.open_file("/etc/group")?;
 
    // Copy the file contents to stdout
    let mut stdout = io::stdout().lock();
    io::copy(&mut file_reader, &mut stdout)?;
    Ok(())
}

Feature Flags

Squinter uses feature flags to select compression algorithms for inclusion:

• gzip - Include support for GZIP compression via flate2 (default)
• xz - Include support for XZ compression via lzma-rs (default)
• zstd - Include support for ZSTD compression via ruzstd (default)

no_std support

Squinter does not currently support no_std, but it doesn’t have any deep dependencies on std, either. no_std could likely be implemented with minimal effort.
