Struct ProviderChainError 

pub struct ProviderChainError<E: Error> { /* private fields */ }

Error returned when all providers in a chain are exhausted without producing credentials or tokens.

Contains per-provider errors for programmatic inspection via ProviderChainError::attempts.

To access from a CredentialsError or TokenError, downcast the error source:

use aws_config::meta::ProviderChainError;
use aws_credential_types::provider::error::CredentialsError;
use std::error::Error;

if let Some(chain_err) = err.source()
    .and_then(|s| s.downcast_ref::<ProviderChainError<CredentialsError>>())
{
    for attempt in chain_err.attempts() {
        println!("{}: {}", attempt.name(), attempt.error());
    }
}

Implementations

impl<E: Error> ProviderChainError<E>

pub fn attempts(&self) -> &[ProviderAttempt<E>]

Returns the per-provider errors in chain order.

Trait Implementations

impl<E: Debug + Error> Debug for ProviderChainError<E>

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

Formats the value using the given formatter.

impl<E: Error> Display for ProviderChainError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for ProviderChainError<E>

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
