Why resolution failed.

Variants

NotFound

No document at the URL.

Fields

url: String

The URL that was requested.

Transport

The transport could not complete the request.

Fields

url: String

The URL that was requested.

message: String

What the transport reported.

Malformed

The body was not a DID document.

Fields

url: String

The URL that was requested.

message: String

What the deserializer reported.

IdMismatch

The document’s id is not the DID that was asked for.

The spec is blunt about this: “The DID declared in the document (in the id field) should always be verified against what was expected.” Skipping it means accepting a document that claims to be a different account, which for did:web is whatever the host chose to serve.

Fields

url: String

The URL that was requested.

expected: String

The DID that was asked for.

found: String

The DID the document claimed.

InvalidDid

The DID is not a legal one of its own method — a malformed did:web or a did:plc whose identifier is not base32-sortable. Caught before any fetch: an unvalidated identifier joined into a URL is how a resolver ends up requesting something other than a DID document.

Fields

did: String

The DID that failed to parse.

method: String

The method it claimed, e.g. "did:web".

message: String

What was wrong with it.

UnsupportedMethod

The DID’s method is not one this resolver speaks.

Named explicitly rather than folded into Self::NotFound: a method this resolver has no path for and a document that genuinely does not exist are different facts, and a caller deciding whether to keep polling needs to tell them apart.

Fields

did: String

The full DID that was requested.

method: String

The method it named.

Trait Implementations

impl Clone for ResolveError

fn clone(&self) -> ResolveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ResolveError

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

Formats the value using the given formatter.

impl Display for ResolveError

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

Formats the value using the given formatter.

impl Error for ResolveError

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 PartialEq for ResolveError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
