Struct ServerError 

pub struct ServerError { /* private fields */ }

Error answer to a call.

It is sent as trailers: grpc-status, grpc-message and any extra headers. Hand-written services return it directly. With #[server], a method returns it to fail the call (see MethodResult and StreamResult); it is also produced for unknown methods and requests that cannot be decoded.

Implementations

impl ServerError

pub fn new( status: GrpcStatus, message: HeaderValue, headers: Option<HeaderMap>, ) -> Self

Create an error from a status, a grpc-message text and extra trailers.

The message is sent as is. The gRPC spec expects it to be percent-encoded, build it with encode_grpc_message().

Trait Implementations

impl Clone for ServerError

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 ServerError

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

Formats the value using the given formatter.

impl Display for ServerError

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

Formats the value using the given formatter.

impl Error for ServerError

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<DecodeError> for ServerError

fn from(_: DecodeError) -> Self
