Expand description

Error type for all TUF related errors.

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.

`BadSignature`

The metadata had a bad signature.

`Encoding(String)`

There was a problem encoding or decoding.

`ExpiredMetadata(Role)`

Metadata was expired.

`IllegalArgument(String)`

An illegal argument was passed into a function.

`Http(Error)`

Generic error for HTTP connections.

`BadHttpStatus`

Fields

code: StatusCode

HTTP status code.

uri: String

URI Resource that resulted in the error.

Unexpected HTTP response status.

`Hyper(Error)`

Errors that can occur parsing HTTP streams.

`MissingMetadata(Role)`

The metadata was missing, so an operation could not be completed.

`NoSupportedHashAlgorithm`

There were no available hash algorithms.

`NotFound`

The metadata or target was not found.

`Opaque(String)`

Opaque error type, to be interpreted similar to HTTP 500. Something went wrong, and you may or may not be able to do anything about it.

`Programming(String)`

There was a library internal error. These errors are ALWAYS bugs and should be reported.

`TargetUnavailable`

The target is unavailable. This may mean it is either not in the metadata or the metadata chain to the target cannot be fully verified.

`UnknownKeyType(String)`

There is no known or available key type.

`VerificationFailure(String)`

The metadata or target failed to verify.
