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;

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 + 'static,
    T: Transform<S, Request = S::Request, Response = S::Response, Error = S::Error>,
    T::Future: 'static,
    T::InitError: 'static,
    T::Transform: 'static, 

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 transform service.

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

The TransformService value created by this factory

type Future = LocalBoxFuture<'static, Result<Self::Transform, Self::InitError>>

The future response value.

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

Creates and returns a new Transform component, asynchronously

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

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