Errors fetching a KEL over HTTP from an OOBI endpoint.

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.

InvalidUrl(String)

The base URL or constructed OOBI URL is malformed.

InsecureScheme(String)

The URL scheme is not https (SSRF guard; bypassed only when private hosts are explicitly allowed).

BlockedHost(String)

The target host is loopback / private / link-local (SSRF guard).

Request(String)

The HTTP request itself failed (DNS, connect, TLS, timeout).

NotFound

404 — the host serves no KEL for this identifier.

Gone

410 — the identity is gone (revoked/abandoned at the host).

RateLimited

429 — rate limited.

ServerPrefixMismatch

422 — the server itself reported a prefix mismatch.

UnexpectedStatus(u16)

Any other non-success status.

Oversized(usize)

The response exceeded the size cap.

Malformed(String)

The body was not a parseable KEL.

Trait Implementations

impl Debug for HttpOobiError

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

Formats the value using the given formatter.

impl Display for HttpOobiError

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

Formats the value using the given formatter.

impl Error for HttpOobiError

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.
