+/// # fn main() -> Result<(), RucteError> { +/// let mut ructe = Ructe::from_env()?; +/// ructe.statics()?.add_files("static")?; +/// # Ok(()) +/// # } +/// ``` +/// +/// Then you need to link to the encoded file. +/// For an image, you probably want to link it from an `` tag in +/// a template. That can be done like this: +/// +/// ```html +/// @use super::statics::image_png; +/// @() +/// Something +/// ``` +/// +/// So, what has happened here? +/// First, assuming the `static` directory in your +/// `$CARGO_MANIFEST_DIR` contained a file name `image.png`, your +/// `templates::statics` module (which is reachable as `super::statics` +/// from inside a template) will contain a +/// `pub static image_png: StaticFile` which can be imported and used +/// in both templates and rust code. +/// A `StaticFile` has a field named `name` which is a `&'static str` +/// containing the name with the generated hash, `image-SomeHash.png`. +/// +/// The next step is that a browser actually sends a request for +/// `/static/image-SomeHash.png` and your server needs to deliver it. +/// Here, things depend on your web framework, so we start with some +/// pseudo code. +/// Full examples for [warp], [gotham], [nickel], and [iron] is +/// available [in the ructe repository]. +/// +/// [warp]: https://crates.rs/crates/warp +/// [gotham]: https://crates.rs/crates/gotham +/// [nickel]: https://crates.rs/crates/nickel +/// [iron]: https://crates.rs/crates/iron +/// [in the ructe repository]: https://github.com/kaj/ructe/tree/master/examples +/// +/// ```ignore +/// /// A hypothetical web framework calls this each /static/... request, +/// /// with the name component of the URL as the name argument. +/// fn serve_static(name: &str) -> Response { +/// if let Some(data) = StaticFile::get(name) { +/// Response::Ok(data.content) +/// } else { +/// Response::NotFound +/// } +/// } +/// ``` +/// +/// The `StaticFile::get` function returns the `&'static StaticFile` +/// for a given file name if the file exists. +/// This is a reference to the same struct that we used by the name +/// `image_png` in the template. +/// Besides the `name` field (which will be equal to the argument, or +/// `get` would not have returned this `StaticFile`), there is a +/// `content: &'static [u8]` field which contains the actual file +/// data. +/// +/// # Content-types +/// +/// How to get the content type of static files. +/// +/// Ructe has support for making the content-type of each static +/// file availiable using the +/// [mime](https://crates.io/crates/mime) crate. +/// Since mime version 0.3.0 was a breaking change of how the +/// `mime::Mime` type was implemented, and both Nickel and Iron +/// currently require the old version (0.2.x), ructe provides +/// support for both mime 0.2.x and mime 0.3.x with separate +/// feature flags. +/// +/// # Mime 0.2.x +/// +/// To use the mime 0.2.x support, enable the `mime02` feature and +/// add mime 0.2.x as a dependency: +/// +/// ```toml +/// [build-dependencies] +/// ructe = { version = "^0.3.2", features = ["mime02"] } +/// +/// [dependencies] +/// mime = "~0.2" +/// ``` +/// +/// A `Mime` as implemented in `mime` version 0.2.x cannot be +/// created statically, so instead a `StaticFile` provides +/// `pub fn mime(&self) -> Mime`. +/// +/// ``` +/// # // Test and doc even without the feature, so mock functionality. +/// # pub mod templates { pub mod statics { +/// # pub struct FakeFile;
