Error type for all TUF related errors.

Variants

CanonicalJsonError(String)

Errors for converting JSON to canonical JSON.

ExpiredMetadata(Role)

The metadata for the given role has expired.

Generic(String)

Generic error type for more opaque error reporting.

Http(String)

An HTTP or network error.

InvalidConfig(String)

The TUF configuration was invalid.

Io(String)

Wrapper for IO errors.

Json(String)

There was an error parsing JSON.

MetadataHashMismatch(Role)

The calculated and provided hashes for the matadata did not match.

MissingMetadata(Role)

A necessary piece of metadata was missing.

NonUniqueSignatures

The signed metadata had duplicate signatures from a particular key.

NoSupportedHashAlgorithms

The metadata did not provide any hash algorithms that this library can calculate.

OversizedMetadata(Role)

A piece of metadata exceeded the provided or maximum allowed size.

OversizedTarget

The targets exceeded the provided size.

TargetHashMismatch

The calculated and provided hashes for the target did not match.

UnknownRole(String)

An unknown role type was parsed and rejected.

UnknownTarget

The target does not exist in valid metadata.

UnmetThreshold(Role)

The role did not have enough signatures to meet the required threshold.

UnsupportedKeyType(String)

The key type was not supported by this library.

UnsupportedSignatureScheme(String)

The signature scheme was not supported by this library.

VerificationFailure(String)

There was an error in the verification process.

VersionDecrease(Role)

A piece of metadata decreased its version when not allowed.
