Enum ExternalProviderError 

#[non_exhaustive]
pub enum ExternalProviderError {
    Unavailable,
    Credentials,
    Object,
    Usage,
    Binding,
    Operation,
}

Operational failure classes for an explicitly selected external provider.

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.

Unavailable

The module, token or device is unavailable.

Credentials

Authentication failed or the operation requires authentication.

Object

The selected object does not exist, is ambiguous, or has expired.

Usage

Token key usage does not authorize this primitive.

Binding

The key and selected provider do not share an execution domain.

Operation

A provider-side operation or synchronization failed.

impl Eq for ExternalProviderError

impl Error for ExternalProviderError

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.
