Enum ProxyError 

pub enum ProxyError {
    Upstream(Error),
    BadRequestBody,
    BadRequest(String),
    Engine(String),
    NotFound(String),
    Internal(String),
}

Errors that can surface on the request path.

Variants

Upstream(Error)

The upstream provider could not be reached, or returned something unusable (connection failure, timeout, decode error).

BadRequestBody

The inbound request body could not be read (e.g. the connection dropped mid-body).

BadRequest(String)

The request body was malformed for the target wire API (enforce mode parses it).

Engine(String)

The escalation engine could not serve any output (every rung errored).

NotFound(String)

A referenced resource does not exist (e.g. feedback for an unknown trace id).

Internal(String)

An internal failure (e.g. the trace store errored). Never leaks internals to the caller.

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

Formats the value using the given formatter.

impl Error for ProxyError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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.

impl From<Error> for ProxyError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl IntoResponse for ProxyError

fn into_response(self) -> Response

Create a response.
