fs_undo

Reversible filesystem operations for Rust.

Wraps standard filesystem operations in the enum FsOp, which enables reversal of the operation. The Undo trait is implemented for both FsOp and Vec<FsOp> to allow for easy reversal of an operation or a list of operations in reverse order.

On execute(), all information needed to fully restore the state before the operation is queried and stored in memory. Not efficient, but useful for scripts that operate on a limited number of filesystem entries and want to easily restore the initial filesystem state, e.g. on error.

Symlinks are only supported on Unix systems.

Example

use fs_undo::{fs_op::FsOp, undo::Undo};

fn main() -> std::io::Result<()> {
	let mut op = FsOp::copy_file("a.txt", "b.txt");
	op.execute()?;
	op.undo()
}
