Struct PermissionService 

pub struct PermissionService<F, Args, P1, P1Args>
where
    F: Handler<Args>,
    Args: FromRequest,
    F::Output: Responder,
    P1: Permission<P1Args>,
    P1Args: FromRequest,
{ /* private fields */ }

Service that intercepts a request and validates it with a permission. If permission fails, deny_handler is called. If permission succeeds, request is proxied to handler.

Properties

• handler - handler, a function that returns http (serializable) response.
• pd_handler - marker for handler type args, needed to avoid warnings of unused Args.
• deny_handler - function argument, called when permission check is false.
• permission - permission
• pd_permission - marker for permission type args, needed to avoid warnings of unused P1Args.
• ready - flag that tells if future in call is completed or pending.

Implementations

impl<F, Args, P1, P1Args> PermissionService<F, Args, P1, P1Args>

where F: Handler<Args>, Args: FromRequest, P1: Permission<P1Args>, P1Args: FromRequest, F::Output: Responder,

pub fn new( permission: P1, handler: F, deny_handler: fn(HttpRequest) -> HttpResponse, ) -> Self

Creates new PermissionService.

Trait Implementations

impl<F, Args, P1, P1Args> Service<ServiceRequest> for PermissionService<F, Args, P1, P1Args>

where F: Handler<Args>, Args: FromRequest, P1: Permission<P1Args>, P1Args: FromRequest, F::Output: Responder,

type Response = ServiceResponse

Responses given by the service.

type Error = Infallible

Errors produced by the service when polling readiness or executing call.

type Future = Pin<Box<dyn Future<Output = Result<<PermissionService<F, Args, P1, P1Args> as Service<ServiceRequest>>::Response, <PermissionService<F, Args, P1, P1Args> as Service<ServiceRequest>>::Error>>>>

The future response value.

fn poll_ready(&self, _: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Ready when the service is able to process requests.

fn call(&self, args: ServiceRequest) -> Self::Future

Process the request and return the response asynchronously.
