Struct actix_web::middleware::Condition

pub struct Condition<T> { /* fields omitted */ }

Middleware for conditionally enables another middleware. The controled middleware must not change the Service interfaces. This means you cannot control such middlewares like Logger or Compress.

Usage

use actix_web::middleware::{Condition, NormalizePath};
use actix_web::App;

fn main() {
    let enable_normalize = std::env::var("NORMALIZE_PATH") == Ok("true".into());
    let app = App::new()
        .wrap(Condition::new(enable_normalize, NormalizePath));
}

Methods

impl<T> Condition<T>

pub fn new(enable: bool, trans: T) -> Self

Trait Implementations

impl<S, T> Transform<S> for Condition<T> where
    S: Service,
    T: Transform<S, Request = S::Request, Response = S::Response, Error = S::Error>, 

type Request = S::Request

Requests handled by the service.

type Response = S::Response

Responses given by the service.

type Error = S::Error

Errors produced by the service.

type InitError = T::InitError

Errors produced while building a service.

type Transform = ConditionMiddleware<T::Transform, S>

The TransformService value created by this factory

type Future = Either<Map<T::Future, fn(_: T::Transform) -> Self::Transform>, FutureResult<Self::Transform, Self::InitError>>

The future response value.

fn new_transform(&self, service: S) -> Self::Future

Creates and returns a new Service component, asynchronously

fn map_init_err<F, E>(self, f: F) -> TransformMapInitErr<Self, S, F, E> where
    F: Fn(Self::InitError) -> E, 

Map this service's factory error to a different error, returning a new transform service factory.

fn from_err<E>(self) -> TransformFromErr<Self, S, E> where
    E: From<Self::InitError>, 

Map this service's init error to any error implementing From for this services Error`.
