Enum GrpcError 

#[non_exhaustive]
pub enum GrpcError {
    Config(ConfigError),
    Bind {
        addr: SocketAddr,
        source: Error,
    },
    Reflection(String),
    Tls(String),
    DuplicateService(String),
    NotIdle(Lifecycle),
    SharedListenerTaken(String),
    SharedListenerNeedsH2(&'static str),

    DoubleWithoutClient(String),
    ClientSetup {
        name: String,

    AlreadyStarted,
}

A startup failure. Each one aborts boot.

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.

Config(ConfigError)

The configuration is not valid.

Bind

The listener could not bind.

Fields

addr: SocketAddr

The address from bind.

source: Error

The OS error.

Reflection(String)

A reflection descriptor set is not valid.

Tls(String)

TLS could not be set up.

DuplicateService(String)

Two services have the same name, or a user service has the name of a plugin service (health or reflection).

NotIdle(Lifecycle)

The server is not in Idle: a shutdown came before or during start.

SharedListenerTaken(String)

Another plugin (its config section) uses the shared listener.

SharedListenerNeedsH2(&'static str)

Autumn’s TLS listener does not offer HTTP/2 (ALPN h2).

DuplicateClient(String)

Two registrations use one client name: with one type in one plugin, or in two plugins.

ClientWithoutEndpoint

A registered client has no endpoint and no test double.

Fields

name: String

The client name.

section: String

The config section of the plugin.

DoubleWithoutClient(String)

A test double names a client that is not registered.

ClientSetup

A client channel could not be set up (for example, a TLS file).

Fields

name: String

The client name.

message: String

The problem.

AlreadyStarted

The startup hook ran twice.

Trait Implementations

impl Debug for GrpcError

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

Formats the value using the given formatter.

impl Display for GrpcError

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

Formats the value using the given formatter.

impl Error for GrpcError

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<ConfigError> for GrpcError

fn from(source: ConfigError) -> Self

Converts to this type from the input type.
