__This crate is current a work-in-progress. There are many missing header implementations, and it builds against the upcoming, unreleased branch for `axum`.__ const values for all of the htmx headers, so there's no need to mess with
strings in your handlers.

## Extractors
All of the [htmx request headers](https://htmx.org/reference/#request_headers)
have a supported extractor. Additionally, all extractors are infallible, meaning
they will always succeed and never return an error. If the header is not
present, the extractor will return `None` or `false` in most cases.
| Header | Extractor | Value |
| --- | --- | --- |
| `HX-Boosted` | `HxBoosted` | `bool` |
| `HX-Current-URL` | `HxCurrentUrl` | `Option<String>` |
| `HX-History-Restore-Request` | `HxHistoryRestoreRequest` | `bool` |
| `HX-Prompt` | `HxPrompt` | `Option<String>` |
| `HX-Request` | `HxRequest` | `bool` |
| `HX-Target` | `HxTarget` | `Option<String>` |
| `HX-Trigger-Name` | `HxTriggerName` | `Option<String>` |
| `HX-Trigger` | `HxTrigger` | `Option<String>` |
## Examples ## Examples
In this example, we'll look for the `HX-Boosted` header, which is set when applying the [hx-boost](https://htmx.org/attributes/hx-boost/) attribute to an element. In our case, we'll use it to determine what kind of response we send. In this example, we'll look for the `HX-Boosted` header, which is set when

When is this useful? When using a templating engine, like [minijinja](https://github.com/mitsuhiko/minijinja), it is common to extend different templates from a `_base.html` template. However, htmx works by sending partial responses, so extending our `_base.html` would result in lots of extra data being sent over the wire. When is this useful? When using a templating engine, like

If we wanted to swap between pages, we would need to support both full template responses and partial responses _(as the page can be accessed directly or through a boosted anchor)_, so we look for the `HX-Boosted` header and extend from a `_partial.html` template instead.

You can also take advantage of const header values:
```rs
let mut headers = HeaderMap::new();
headers.insert(HX_REDIRECT, HeaderValue::from_static("/some/other/page"));
