Enum DereferenceError 

#[non_exhaustive]
pub enum DereferenceError {
    Resolution {
        did: Did,
        error: ResolutionError,
    },
    InvalidDidUrl {
        url: DidUrl,
        reason: String,
    },
    MethodSpecific(DidUrl),
    Deactivated(Did),
    NotFound(DidUrl),
    NotVerificationMethod(DidUrl),
    NotInRelationship {
        id: DidUrl,
        relationship: VerificationRelationship,
    },
    NoJwk {
        id: DidUrl,
        method_type: MethodType,
        source: Box<JwkError>,
    },
}

Why a DID URL could not be dereferenced.

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.

Resolution

Resolving the DID of the URL failed.

Fields

did: Did

The DID that was resolved.

error: ResolutionError

What went wrong.

InvalidDidUrl

The URL is syntactically valid but not usable: a DID parameter is given twice.

Fields

url: DidUrl

The URL.

reason: String

What is wrong with it.

MethodSpecific(DidUrl)

The URL has a path or query parameter whose meaning only its DID method defines; this crate dereferences none of them (the service and relativeRef parameters included).

Deactivated(Did)

The DID has been deactivated, so none of its resources may be used.

NotFound(DidUrl)

No verification method or service of the document has the id of the URL.

NotVerificationMethod(DidUrl)

The URL names the document or a service, not a verification method.

NotInRelationship

The verification method exists but is not usable for the required relationship.

Fields

id: DidUrl

The id of the verification method.

relationship: VerificationRelationship

The relationship that was required.

NoJwk

The verification method has no publicKeyJwk and its publicKeyMultibase is not a Multikey this crate can decode (see Jwk::from_multikey).

Fields

id: DidUrl

The id of the verification method.

method_type: MethodType

Its type.

source: Box<JwkError>

Why the multibase material did not decode.

Trait Implementations

impl Clone for DereferenceError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DereferenceError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DereferenceError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DereferenceError

impl Error for DereferenceError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<DereferenceError> for KeyResolutionError

fn from(error: DereferenceError) -> Self

Converts to this type from the input type.

impl PartialEq for DereferenceError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
