Struct Context 

pub struct Context { /* private fields */ }

Per-request context passed to every action.

Implementations

impl Context

pub async fn build(req: Request) -> Self

Central constructor used by the #[controller] macro. Splits the request, captures matched path params, and retains the body for later reads.

pub fn from_request_parts(parts: Parts) -> Self

pub fn from_request(parts: Parts, body: Body) -> Self

pub fn db(&self) -> &'static DatabaseConnection

The application’s database connection (global pool installed at boot).

pub fn param(&self, name: &str) -> Option<&str>

A matched path parameter by name, e.g. ctx.param("id") for /posts/{id}.

pub async fn form<T: DeserializeOwned>(&mut self) -> Result<T>

Deserialize a URL-encoded (form) request body. Consumes the body.

pub async fn body_json<T: DeserializeOwned>(&mut self) -> Result<T>

Deserialize a JSON request body. Consumes the body.

pub fn params<T: DeserializeOwned>(&self) -> Result<T>

Deserialize typed params from the request URI query string.

pub fn render(&self, template: &str, data: Value) -> Response

Render a Tera view to an HTML 200 response.

template is resolved by the global doido_view engine (installed at boot) against app/views, with the .html.tera suffix added — e.g. "posts/index" → app/views/posts/index.html.tera. A render failure (or an uninitialised engine) yields a 500.

pub fn json<T: Serialize>(&self, data: T) -> Response

Return a JSON 200 response.

pub fn redirect_to(&self, location: impl AsRef<str>) -> Response

Return a 302 redirect.

pub fn status(&self, code: u16) -> Response

Return a response with an explicit status code and empty body. code must be a valid HTTP status code (100–999).

pub fn header(&self, name: &str) -> Option<&HeaderValue>

Get a request header by name (lowercase).
