Enum ProtocolError 

pub enum ProtocolError {
    Config(String),
    Transport(Error),
}

Error raised while building the configuration or the channel. No request was sent yet.

The connectors turn it into brokapi_core::Error::Config at start. It never describes a failed call: calls fail with a tonic::Status.

Variants

Config(String)

The configuration cannot be used: the token or the app name has characters a header cannot carry, or the endpoint is not a valid URL. Fix the value, retrying changes nothing.

Transport(Error)

The transport could not be set up (for example the TLS configuration was refused). The channel connects lazily, so an unreachable server is not reported here but on the first call.

Trait Implementations

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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 ProtocolError

fn from(source: Error) -> Self

Converts to this type from the input type.
