Struct ErrorPages 

pub struct ErrorPages { /* private fields */ }

The error-page middleware. See the module docs.

Implementations

impl ErrorPages

pub fn from_env() -> ErrorPages

Details per RWS_ENV: on in dev and test, off in prod (and when it’s unset).

pub fn detailed(details: bool) -> ErrorPages

Details on or off, whatever RWS_ENV says.

pub fn shows_details(&self) -> bool

Whether the client sees the details.

Trait Implementations

impl Clone for ErrorPages

fn clone(&self) -> ErrorPages

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ErrorPages

impl Debug for ErrorPages

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Middleware for ErrorPages

fn handle( &self, request: &Request, connection: &ConnectionInfo, next: &dyn Application, ) -> Result<Response, String>

fn is_passthrough( &self, _request: &Request, _connection: &ConnectionInfo, ) -> bool

true when handle would do nothing for request but call next (e.g. a rate limit that isn’t configured). A WithMiddleware stack offers the inner application’s execute_async only if every layer passes the request through. Default false.

fn runs_inline(&self, _request: &Request, _connection: &ConnectionInfo) -> bool

true when this layer’s own work for request never blocks (in-memory state, atomics, short mutexes) — see Application::runs_inline. A WithMiddleware stack runs inline only if every layer and the inner application agree. Default false.

fn accepts_streamed_body( &self, _request: &Request, _connection: &ConnectionInfo, ) -> bool

true when this layer never reads request.body, so the inner application may receive it as a stream (Application::streams_body). A layer that inspects the body (CSRF tokens in a form, request signatures, rewriting) must keep the default false: it would see an empty body.

fn layer_name(&self) -> &'static str

A short name for this layer, as tools that describe an app list it (Application::middleware_names): by default the type’s name without its module path or generic parameters (CacheLayer). Since 18.28.0.

fn answers_streamed_body( &self, _request: &Request, _connection: &ConnectionInfo, ) -> bool

true when this layer answers request itself — it doesn’t call next — and reads its body as a stream (a proxy forwarding it as it arrives). The body is then streamed whatever the layers after it and the application would say. Requires accepts_streamed_body. Since 18.3.0.
