Struct actix_request_identifier::RequestIdentifier

pub struct RequestIdentifier { /* fields omitted */ }

A middleware for generating per-request unique IDs

Methods

impl RequestIdentifier

pub fn with_uuid() -> Self

Create a default middleware using DEFAULT_HEADER as the header name and UUID v4 for ID generation.

pub fn with_header(header_name: &'static str) -> Self

Create a middleware using a custom header name and UUID v4 for ID generation.

pub fn header(self, header_name: &'static str) -> Self

Change the header name for this middleware.

pub fn with_generator(id_generator: fn() -> HeaderValue) -> Self

Create a middleware using DEFAULT_HEADER as the header name and IDs as generated by id_generator. id_generator should return a unique ID (ASCII only), each time it is invoked.

pub fn generator(self, id_generator: fn() -> HeaderValue) -> Self

Change the ID generator for this middleware.

Trait Implementations

impl Default for RequestIdentifier

fn default() -> Self

Returns the "default value" for a type.

impl<S, B> Transform<S> for RequestIdentifier where
    S: Service<Request = ServiceRequest, Response = ServiceResponse<B>, Error = ActixError>,
    S::Future: 'static,
    B: '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 = ()

Errors produced while building a transform service.

type Transform = RequestIdMiddleware<S>

The TransformService value created by this factory

type Future = Ready<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.
