Struct MaintenanceLayer 

pub struct MaintenanceLayer;

Middleware that returns 503 when MAINTENANCE_MODE is true.

Health probe paths (/healthz, /readyz) always pass through so that load balancers can still detect the pod is alive.

Trait Implementations

impl Middleware for MaintenanceLayer

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

Headers only: a streamed body passes through untouched.

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

In-memory only: safe on the event loop.

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.
