Module tower_web::extract

Extract data from the HTTP request.

The Extract trait is implemented by types that can be constructed by using data from an HTTP request. Resource method argument types must implement Extract. This is how impl_web! is able to instantiate them using the request. See library level documentation for more details.

Currently, Extract implementations are provided for the following types:

• Bytes
• Option
• PathBuf
• String
• Vec<u8>

More implementations can be added by submitting a PR.

Also, Extract can be implemented for custom types by using the [derive(Extract)] proc macro. See library level documentation for more details.
