Enum aws_credential_types::provider::error::TokenError

pub enum TokenError {
    TokenNotLoaded(TokenNotLoaded),
    ProviderTimedOut(ProviderTimedOut),
    InvalidConfiguration(InvalidConfiguration),
    ProviderError(ProviderError),
    Unhandled(Unhandled),
}

Error returned when an access token provider fails to provide an access token.

Variants

TokenNotLoaded(TokenNotLoaded)

This provider couldn’t provide a token.

ProviderTimedOut(ProviderTimedOut)

Loading a token from this provider exceeded the maximum allowed time.

InvalidConfiguration(InvalidConfiguration)

The provider was given invalid configuration.

For example, a syntax error in ~/.aws/config.

ProviderError(ProviderError)

The provider experienced an error during credential resolution.

Unhandled(Unhandled)

An unexpected error occurred during token resolution.

If the error is something that can occur during expected usage of a provider, ProviderError should be returned instead. Unhandled is reserved for exceptional cases, for example:

• Returned data not UTF-8
• A provider returns data that is missing required fields

Implementations

impl TokenError

pub fn not_loaded( source: impl Into<Box<dyn Error + Send + Sync + 'static>> ) -> Self

The access token provider couldn’t provide a token.

This error indicates the token provider was not enable or no configuration was set. This contrasts with invalid_configuration, indicating that the provider was configured in some way, but certain settings were invalid.

pub fn unhandled( source: impl Into<Box<dyn Error + Send + Sync + 'static>> ) -> Self

An unexpected error occurred loading an access token from this provider.

Unhandled errors should not occur during normal operation and should be reserved for exceptional cases, such as a JSON API returning an output that was not parseable as JSON.

pub fn provider_error( source: impl Into<Box<dyn Error + Send + Sync + 'static>> ) -> Self

The access token provider returned an error.

pub fn invalid_configuration( source: impl Into<Box<dyn Error + Send + Sync + 'static>> ) -> Self

The provided configuration for a provider was invalid.

pub fn provider_timed_out(timeout_duration: Duration) -> Self

The access token provider did not provide a token within an allotted amount of time.

Trait Implementations

impl Debug for TokenError

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

Formats the value using the given formatter.

impl Display for TokenError

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

Formats the value using the given formatter.

impl Error for TokenError

fn source(&self) -> Option<&(dyn Error + 'static)>

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
