Types

type InvalidExtensionError

type InvalidExtensionError struct {
	// contains filtered or unexported fields
}

InvalidExtensionError is an error for invalid extension of the state. An invalid extension is distinct from outdated or unverifiable extensions, in that it indicates a malicious input.

func (InvalidExtensionError) Unwrap

func (e InvalidExtensionError) Unwrap() error

type OutdatedExtensionError

type OutdatedExtensionError struct {
	// contains filtered or unexported fields
}

OutdatedExtensionError is an error for the extension of the state being outdated. Being outdated doesn't mean it's invalid or not. Knowing whether an outdated extension is an invalid extension or not would take more state queries.

func (OutdatedExtensionError) Unwrap

func (e OutdatedExtensionError) Unwrap() error

type UnverifiableExtensionError

type UnverifiableExtensionError struct {
	// contains filtered or unexported fields
}

UnverifiableExtensionError represents a state extension (block) which cannot be verified at the moment. For example, it does not connect to the finalized state, or an entity referenced within the payload is unknown. Unlike InvalidExtensionError, this error is only used when the failure CANNOT be attributed to a malicious input, therefore this error can be treated as a benign failure.

func (UnverifiableExtensionError) Unwrap

func (e UnverifiableExtensionError) Unwrap() error
