Function dptree::from_fn

pub fn from_fn<'a, F, Fut, Input, Output, Descr>(
    f: F
) -> Handler<'a, Input, Output, Descr> where
    F: Fn(Input, Cont<'a, Input, Output>) -> Fut,
    F: Send + Sync + 'a,
    Fut: Future<Output = ControlFlow<Output, Input>> + Send + 'a,
    Descr: HandlerDescription, 

Constructs a handler from a function.

Most of the time, you do not want to use this function. Take a look at more specialised functions: crate::endpoint, crate::filter, crate::filter_map, etc.
