Errors returned by the connection helpers in this module.

Variants

EmptyToken

dial_admin was called with an empty (or whitespace-only) token.

InvalidCaPem

A CA PEM bundle was supplied but contained no parseable certificates.

ForceTlsPlaintextConflict

dial_admin was called with both force_tls and plaintext set. They request opposite overrides of the loopback heuristic, so exactly one (or neither) may be set. See dial_admin’s doc comment.

PlaintextCaPemConflict

dial_admin was called with plaintext set and a non-empty ca_pem. There is no meaningful CA to verify against when the transport isn’t TLS at all. See dial_admin’s doc comment.

CaPemParse(String)

A CA PEM bundle was supplied but failed to parse.

InvalidEndpoint

The target address could not be turned into a valid gRPC endpoint URI.

Fields

addr: String

source: Error

Connect

Failed to establish the transport connection.

Fields

addr: String

source: Error

ReadCaFile

Reading a CA bundle from disk (see read_ca_file) failed.

Fields

path: String

source: Error

Trait Implementations

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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.
