Enum VtcError 

pub enum VtcError {
    NotAuthenticated,
    Http {
        status: u16,
        body: String,
    },
    Url(String),
    Transport(Error),
    Auth(VtaError),
    Unsupported(&'static str),
    Signing(String),
    Session(String),
    NoRestTransport(&'static str),
}

Errors surfaced by the VTC client.

Variants

NotAuthenticated

A request needed a bearer token but the client has none — call VtcClient::connect (or construct via VtcClient::with_token).

Http

The VTC returned a non-success HTTP status.

Fields

status: u16

body: String

Url(String)

A request URL could not be built.

Transport(Error)

A transport-level error talking to the VTC.

Auth(VtaError)

Challenge-response authentication failed.

Unsupported(&'static str)

The operation’s route no longer exists on the VTC and this client has no replacement for it. Carries what to use instead.

Signing(String)

Building or signing a holder Trust Task failed — e.g. an applicant DID that is not a did:key passed to the did:key convenience wrapper, a verification method with no fragment, or an undecodable private key.

Session(String)

Opening or using a messaging session to the VTC failed.

Distinct from Transport, which is HTTPS: a mediator that will not route and a URL that will not resolve are different faults with different fixes, and one error that covered both would send the reader to the wrong half of the system.

NoRestTransport(&'static str)

A verb that only exists on the HTTPS surface was called on a client built with no REST base.

The admin verbs are gated on a bearer token and a per-route Trust-Task header, which is a URL-shaped surface — they cannot ride a session. Rather than fail at the transport with something obscure, say so: pass rest_url to the connect_* constructor.

Trait Implementations

impl Debug for VtcError

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

Formats the value using the given formatter.

impl Display for VtcError

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

Formats the value using the given formatter.

impl Error for VtcError

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<Error> for VtcError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<VtaError> for VtcError

fn from(source: VtaError) -> Self

Converts to this type from the input type.
