Fields

rate_limit: Option<RateLimitConfig>

cache: Option<CacheConfig>

auth: Option<AuthConfig>

rewrite_request: Vec<RewriteRuleConfig>

rewrite_response: Vec<RewriteRuleConfig>

ip_allow: Vec<String>

ip_deny: Vec<String>

timeout_ms: Option<u64>

timeout_ms — if the route (including all its other middleware) doesn’t produce a response within this many milliseconds, the client gets 504 Gateway Timeout instead of waiting further. See crate::timeout for the underlying mechanism and its limitations.

max_body_size: Option<u64>

max_body_size — reject this route’s request with 413 Payload Too Large if its body exceeds this many bytes.

This is a route-specific ceiling on top of the global, process-wide RWS_CONFIG_MAX_BODY_SIZE_IN_BYTES (see crate::entry_point::get_max_body_size) — e.g. a small JSON API route can be capped stricter than a file-upload route without lowering the global limit for everyone. It is not a substitute for the global limit: by the time any route-level middleware runs, Request (including its body) has already been fully read off the socket — route matching itself requires the complete request, so a per-route check can only run after that memory is already spent, not before. The global limit is what protects total server memory from an oversized upload; max_body_size protects only this route’s own logic/upstream from an oversized-but-still-within-the-global-limit body.

wasm: Option<WasmConfig>

[route.middleware.wasm]: a WebAssembly plugin (feature wasm-plugins, 18.10.0).

early_hints: Vec<String>

early_hints = ["</app.css>; rel=preload; as=style", …]: Link values sent as a 103 Early Hints before the route answers (18.12.0).

authz: Option<RouteAuthzConfig>

[route.middleware.authz]: the caller needs relation on object. Since 18.14.0.

mirror: Option<MirrorConfig>

[route.middleware.mirror]: copy a share of requests to other backends (18.11.0).

waf: Option<WafSettings>

[route.middleware.waf] (18.22.0): the web application firewall.

Implementations

impl MiddlewareConfig

pub fn is_empty(&self) -> bool

true when no layer is configured. A mirror and early hints don’t count: proxy routes send both from DynamicProxy itself, so such a route keeps the non-blocking forwarder.

Trait Implementations

impl Clone for MiddlewareConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MiddlewareConfig

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

Formats the value using the given formatter.

impl Default for MiddlewareConfig

fn default() -> Self

Returns the “default value” for a type.
