Implementations§

Source§

impl Catcher

Source

pub fn new<H>(goal: H) -> Catcher
where H: Handler,

Create new Catcher.

Source

pub fn hoops(&self) -> &Vec<Arc<dyn Handler>>

Get current catcher’s middlewares reference.

Source

pub fn hoops_mut(&mut self) -> &mut Vec<Arc<dyn Handler>>

Get current catcher’s middlewares mutable reference.

Source

pub fn hoop<H>(self, hoop: H) -> Catcher
where H: Handler,

Add a handler as middleware, it will run the handler when error catched.

Source

pub fn hoop_when<H, F>(self, hoop: H, filter: F) -> Catcher
where H: Handler, F: Fn(&Request, &Depot) -> bool + Send + Sync + 'static,
