Crate bux_e2fs 

Ext4 filesystem image creation via libext2fs — static FFI bindings and safe Rust API.

Architecture

• sys — Raw FFI bindings (auto-generated by bindgen).
• Filesystem — RAII wrapper around ext2_filsys with safe operations.
• create_from_dir / inject_file — Convenience functions for common tasks.

Quick Start

use std::path::Path;

let size = bux_e2fs::estimate_image_size(Path::new("/tmp/rootfs")).unwrap();
bux_e2fs::create_from_dir(
    Path::new("/tmp/rootfs"),
    Path::new("/tmp/image.raw"),
    size,
).unwrap();

Modules

sys

Raw FFI bindings to libext2fs and [create_inode].

Structs

Enums

BlockSize

Block size for an ext4 filesystem.

Error

Errors returned by ext4 operations.

FileType

File type for directory entries (maps to EXT2_FT_* constants).

Functions

create_from_dir

Creates an ext4 image populated from a host directory.

estimate_image_size
