fn example() -> ProxyResult<()> {

InvalidProxyUrl

A supplied proxy URL failed validation.

Fields

url: String

The URL that was rejected.

reason: String

Human-readable explanation of the validation failure.

HealthCheckFailed

A health check request for a proxy failed.

Fields

proxy: String

Display form of the proxy URL (credentials redacted).

message: String

Description of the underlying error.

CircuitOpen

The circuit breaker for this proxy is open — calls are being rejected fast.

Fields

proxy: String

Display form of the proxy URL (credentials redacted).

StorageError(String)

Trait Implementations

impl Debug for ProxyError

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

Formats the value using the given formatter.

impl Display for ProxyError

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

Formats the value using the given formatter.

impl Error for ProxyError

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.
