Enum Error 

pub enum Error {
    Problem(Problem),
    TermsNotAgreed,
    KeyChangeConflict {
        holder: Uuid,
    },
}

The error an OrderService or AccountService operation returns.

Most refusals are protocol answers the client is owed verbatim — the type, the status and a detail several test suites pin byte for byte — and those travel as the Problem they already are. Problem is a data type as much as a response: the documents stored in challenges.error and orders.error are its RFC 7807 JSON, and only its IntoResponse impl belongs to the HTTP edge. Rebuilding every ACME error type here as a variant would be a second definition of each, free to drift from the first.

The other two variants exist because the HTTP edge needs data a problem document cannot carry: the Link to the terms of service, and the Location of the account already holding a key. Each still maps to the problem an ACME client would have seen, through From<Error> for Problem.

Variants

Problem(Problem)

A refusal the client reads as it is.

TermsNotAgreed

newAccount without agreeing to the configured terms (RFC 8555 §7.3.3). Its response carries a Link to the terms, which a problem document cannot.

KeyChangeConflict

keyChange onto a key another account holds (RFC 8555 §7.3.5). Its response carries that account’s Location.

Fields

holder: Uuid

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Problem

fn from(error: Error) -> Self

Converts to this type from the input type.

impl From<Problem> for Error

fn from(problem: Problem) -> Self

Converts to this type from the input type.
