Available on crate feature linked-vp only.

Why a linked presentation could not be found, fetched or validated.

Variants (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.

InvalidService

A LinkedVerifiablePresentation service does not name one or more URLs.

Fields

id: DidUrl

The id of the service.

reason: String

What is wrong with it.

UnsupportedEndpoint(Url)

A URL is not https: an ipfs:// endpoint, say. Only HTTPS is fetched.

Http

The HttpClient got no response.

Fields

url: Url

The URL fetched.

source: HttpError

Why there was no response.

HttpStatus

The server answered with a status other than 2xx.

Fields

url: Url

The URL fetched.

status: u16

The status code.

UnsupportedFormat(Url)

The body is a JSON object: a presentation in the JSON-LD form, which this crate does not process.

InvalidBody

The body is not a compact JWT.

Fields

url: Url

The URL fetched.

reason: String

What is wrong with the body.

HolderMismatch

The presentation’s holder is not the DID whose document links it.

Fields

did: Did

The DID linking the presentation.

holder: Did

The holder the presentation names.

Presentation(PresentationValidationError)

The presentation or some of its credentials did not validate.

Validation(ValidationError)

The presentation did not decode, or did not sign.

Resolution(ResolutionError)

The DID did not resolve.

TooManyUrls(usize)

The URL was not fetched: the DID document lists more URLs than the client’s limit, given here.

Trait Implementations
