Enum ProxyError 

pub enum ProxyError {
    Config(String),
    NoRoute(String),
    NoUpstream(String),
}

Errors that can occur during proxy operation.

use praxis_core::ProxyError;

let e = ProxyError::Config("bad yaml".into());
assert_eq!(e.to_string(), "config: bad yaml");

let e = ProxyError::NoRoute("GET /missing".into());
assert_eq!(e.to_string(), "no route for GET /missing");

let e = ProxyError::NoUpstream("backend".into());
assert_eq!(e.to_string(), "no upstream in cluster 'backend'");

Variants

Config(String)

Configuration loading or validation error.

Raised during startup or hot-reload when YAML parsing or validation fails. Not retriable; fix the configuration. The server continues running with the previous config on hot-reload failures.

NoRoute(String)

No route matched the incoming request.

Raised during request routing when no filter chain’s router matches the method, path, and headers. Returns 404 to the client. Not retriable for the same request.

NoUpstream(String)

No upstream available in the given cluster.

Raised when a route matched but all endpoints in the target cluster are unhealthy or the cluster is empty. Returns 503 to the client. Retriable after health checks recover an endpoint.

Trait Implementations

impl Debug for ProxyError

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

Formats the value using the given formatter.

impl Display for ProxyError

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

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
