Core error type for the Camel framework.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ComponentNotFound(String)

EndpointCreationFailed(String)

ProcessorError(String)

ProcessorErrorWithSource(String, Arc<dyn Error + Send + Sync>)

Like ProcessorError but preserves the source error chain for downstream inspection (e.g. via std::error::Error::source()).

TypeConversionFailed(String)

InvalidUri(String)

ChannelClosed

RouteError(String)

Io(String)

DeadLetterChannelFailed(String)

CircuitOpen(String)

HttpOperationFailed

Fields

method: String

url: String

status_code: u16

status_text: String

response_body: Option<String>

ConsumerStopping

Producer call() failed on a shutdown signal — the consumer/semaphore is closing and the producer cannot acquire a permit. Distinct from Stop EIP (which is successful control flow). Used by JMS/OpenSearch producers. See ADR-0024.

Config(String)

ConfigValidation(ConfigValidationError)

Typed security-validation error (ADR-0033). Promotes Batch 1+ config/startup failure modes from stringly-typed Config(_) to a matchable enum so operators can discriminate programmatically.

AlreadyConsumed

StreamLimitExceeded(usize)

Unauthenticated(String)

Unauthorized(String)

AuthProviderUnavailable(String)

Auth provider (JWKS/introspection/token endpoint) is unreachable or failing. Promotes the auth-provider-down signal from a stringly-typed ProcessorError to a matchable variant; WebSocket and gRPC transports map it to 503 / UNAVAILABLE.

ValidationError(String)

TemplateReload(String)

EndpointUri(EndpointUriError)

Typed endpoint-URI construction error (see EndpointUriError). Promotes the fail-closed EndpointUri merge failures from stringly-typed errors to a matchable variant so operators can discriminate programmatically.

UnsupportedMediaType

The request body media type does not match the declared/consumed type (REST DSL default-strict content negotiation, HTTP 415).

Fields

consumed: String

declared: String

NotAcceptable

The response representation cannot satisfy the client’s Accept header (REST DSL default-strict content negotiation, HTTP 406).

Fields

accept: String

produced: String

Implementations

impl CamelError

pub fn classify(&self) -> &'static str

pub fn variant_name(&self) -> &'static str

Stable variant name used by doTry catch-by-variant matchers.

ProcessorErrorWithSource and AuthProviderUnavailable alias to "ProcessorError" — the variants are not distinguishable by name in MVP (see spec §5.4), so existing doTry catch handlers keep matching.

The enum is #[non_exhaustive]; this match lives in the defining crate (camel-api), so internal exhaustive matching is allowed. Adding a new variant without updating this method will fail to compile, surfaced by variant_name_tests.

Trait Implementations

impl Clone for CamelError

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 CamelError

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

Formats the value using the given formatter.

impl Display for CamelError

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

Formats the value using the given formatter.

impl Error for CamelError

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<ConfigValidationError> for CamelError

fn from(e: ConfigValidationError) -> Self

Converts to this type from the input type.

impl From<EndpointUriError> for CamelError

fn from(e: EndpointUriError) -> Self

Converts to this type from the input type.

impl From<Error> for CamelError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<TemplateError> for CamelError

fn from(err: TemplateError) -> Self

Converts to this type from the input type.
