Struct gotham::middleware::logger::RequestLogger

pub struct RequestLogger { /* fields omitted */ }

A struct that can act as a logging middleware for Gotham.

We implement NewMiddleware here for Gotham to allow us to work with the request lifecycle correctly. This trait requires Clone, so that is also included.

Implementations

impl RequestLogger

pub fn new(level: Level) -> Self

Constructs a new RequestLogger instance.

Trait Implementations

impl Clone for RequestLogger

fn clone(&self) -> RequestLogger

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RequestLogger

impl Middleware for RequestLogger

Implementing gotham::middleware::Middleware allows us to hook into the request chain in order to correctly log out after a request has executed.

fn call<Chain>(self, state: State, chain: Chain) -> Pin<Box<HandlerFuture>> where
    Chain: FnOnce(State) -> Pin<Box<HandlerFuture>>, 

Entry point to the middleware. To pass the request on to the application, the middleware invokes the chain function with the provided state.

impl NewMiddleware for RequestLogger

Implementation of NewMiddleware is required for Gotham middleware.

This will simply dereference the internal state, rather than deriving NewMiddleware which will clone the structure - should be cheaper for repeated calls.

type Instance = Self

The type of Middleware created by the NewMiddleware.

fn new_middleware(&self) -> Result<Self::Instance>

Returns a new middleware to be used to serve a request.
