During development it can be very handy to have cargo automatically recompile the code on changes.
|
|
|
|
|
This can be accomplished very easily by using [`cargo-watch`].

```sh

cargo watch -x 'run --bin app'

## Historical Note
|
|
|
|
|
|
|
|
|
|
An old version of this page recommended using a combination of systemfd and listenfd, but this has
|
|
|
|
|
many gotchas and was difficult to integrate properly, especially when part of a broader development
|
|
|
|
|
workflow. We consider [`cargo-watch`] to be sufficient for auto-reloading purposes.
