#[non_exhaustive]
pub enum Error { UrlNotSupported, NotFound, OperationNotSupported, Other(Box<dyn StdError + Sync + Send>), Unknown, }
Expand description

Credential provider error type.

UrlNotSupported and NotFound errors both cause Cargo to attempt another provider, if one is available. The other variants are fatal.

Note: Do not add a tuple variant, as it cannot be serialized.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

UrlNotSupported

Registry URL is not supported. This should be used if the provider only works for some registries. Cargo will try another provider, if available

§

NotFound

Credentials could not be found. Cargo will try another provider, if available

§

OperationNotSupported

The provider doesn’t support this operation, such as a provider that can’t support ‘login’ / ‘logout’

§

Other(Box<dyn StdError + Sync + Send>)

The provider failed to perform the operation. Other providers will not be attempted

§

Unknown

A new variant was added to this enum since Cargo was built
