Struct actix_web::dev::ServiceRequest

pub struct ServiceRequest { /* private fields */ }

A service level request wrapper.

Allows mutable access to request’s internal structures.

Implementations

impl ServiceRequest

pub fn into_parts(self) -> (HttpRequest, Payload)

Deconstruct ServiceRequest into inner parts.

pub fn parts_mut(&mut self) -> (&mut HttpRequest, &mut Payload)

Returns mutable accessors to inner parts.

pub fn parts(&self) -> (&HttpRequest, &Payload)

Returns immutable accessors to inner parts.

pub fn request(&self) -> &HttpRequest

Returns immutable accessor to inner HttpRequest.

pub fn extract<T>(&mut self) -> <T as FromRequest>::Future

where T: FromRequest,

Derives a type from this request using an extractor.

Returns the T extractor’s Future type which can be awaited. This is particularly handy when you want to use an extractor in a middleware implementation.

Examples

use actix_web::{
    dev::{ServiceRequest, ServiceResponse},
    web::Path, Error
};

async fn my_helper(mut srv_req: ServiceRequest) -> Result<ServiceResponse, Error> {

pub fn resource_map(&self) -> &ResourceMap

Returns a reference to the application’s resource map. Counterpart to HttpRequest::resource_map.

pub fn app_config(&self) -> &AppConfig

Counterpart to HttpRequest::app_config.

pub fn set_payload(&mut self, payload: Payload)

Set request payload.

pub fn add_data_container(&mut self, extensions: Rc<Extensions>)

Add data container to request’s resolution set.

In middleware, prefer extensions_mut for request-local data since it is assumed that the same app data is presented for every request.

pub fn guard_ctx(&self) -> GuardContext<'_>

Creates a context object for use with a routing guard.
