`self-replace` is a crate that allows binaries to replace themselves with newer

versions or to uninstall themselves.  On Unix systems this is a simple feat, but

on Windows a few hacks are needed which is why this crate exists.

This is a useful operation when working with single-executable utilties that

want to implement a form of self updating or self uninstallation.

For details about the implementation refer to the [documentation](https://docs.rs/self-replace).

If you are looking for some higher level update logic, have a look at

[`self_update`](https://crates.io/crates/self_update) which uses `self-replace`

under the hood but provides automatic updating from GitHub releases or

other distribution channels.  Note that `self_update` is maintained by

other maintainers.

## Uninstall

To uninstall a binary, use `self_delete`.

```rust

self_replace::self_delete()?;

```

## Updating

To replace a binary for updating, use `self_replace`.

```rust

let new_binary = "/path/to/new/binary";

self_replace::self_replace(&new_binary)?;

std::fs::remove_file(&new_binary)?;

```
