Struct WebIo 

pub struct WebIo { /* private fields */ }

The central Application controller. Manages routing, middleware, and the internal TCP lifecycle.

Implementations

impl WebIo

pub fn new() -> Self

Initializes a new WebIo instance with an empty routing table.

pub fn use_mw<F>(&mut self, f: F)

where F: Fn(&str) -> Option<Reply> + Send + Sync + 'static,

Registers a global middleware function. If the middleware returns Some(Reply), the request cycle ends early.

pub fn on_404<F, Fut>(&mut self, handler: F)

where F: Fn(Req, Params) -> Fut + Send + Sync + 'static, Fut: Future<Output = Reply> + Send + 'static,

Configures custom 404 handlers. It intelligently detects Content-Type to serve JSON or HTML based on the client’s Accept header.

pub fn route<F, Fut>(&mut self, method: Method, path: &str, handler: F)

where F: Fn(Req, Params) -> Fut + Send + Sync + 'static, Fut: Future<Output = Reply> + Send + 'static,

Supports dynamic segments using <name> syntax (e.g., /user/<id>).

pub async fn run(self, host: &str, port: &str)

Starts the blocking TCP listener loop. Spawns a new thread per connection to maintain responsiveness.
