Struct BeforeRequestCons 

pub struct BeforeRequestCons<First, Rest>(/* private fields */);

A list of hooks that run in order before a request is executed.

Trait Implementations

impl<Req, First: BeforeRequest<Req>, Rest: BeforeRequest<Req>> BeforeRequest<Req> for BeforeRequestCons<First, Rest>

async fn before( &mut self, ctx: &mut Context, req: &Req, ) -> Result<(), ServerError>

The function that is called before request execution.

impl<Req, First: BeforeRequest<Req>, Rest: BeforeRequestList<Req>> BeforeRequestList<Req> for BeforeRequestCons<First, Rest>

type Then<Next> = BeforeRequestCons<First, <Rest as BeforeRequestList<Req>>::Then<Next>> where Next: BeforeRequest<Req>

The hook returned by BeforeRequestList::then.

type Serve<S: Serve<Req = Req>> = HookThenServe<S, BeforeRequestCons<First, Rest>>

The service fn returned by BeforeRequestList::serving.

fn then<Next: BeforeRequest<Req>>(self, next: Next) -> Self::Then<Next>

Returns a hook that, when run, runs two hooks, first self and then next.

fn serving<S: Serve<Req = Req>>(self, serve: S) -> Self::Serve<S>

Runs the list of request hooks before execution of the given serve fn. This is equivalent to serve.before(before_request_chain) but may be syntactically nicer.

fn then_fn<Next: FnMut(&mut Context, &Req) -> Fut, Fut: Future<Output = Result<(), ServerError>>>( self, next: Next, ) -> Self::Then<Next>

where Self: Sized,

Same as then, but helps the compiler with type inference when Next is a closure.

impl<First: Clone, Rest: Clone> Clone for BeforeRequestCons<First, Rest>

fn clone(&self) -> BeforeRequestCons<First, Rest>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
