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.

WrongKind(Kind)

The event was not kind: 1985.

MalformedNamespace

An L tag had no namespace value.

MalformedValue

An l tag had no value column.

MalformedEventTarget

An e target tag had no event id column.

MalformedPubkeyTarget

A p target tag had no pubkey column.

MalformedAddressTarget

An a target tag had no coordinate column.

MalformedUrlTarget

An r target tag had no URL column.

MalformedTopicTarget

A t target tag had no topic column.

InvalidEventId(EventIdError)

The e event id could not be parsed.

InvalidPublicKey(PublicKeyError)

The p pubkey could not be parsed.

InvalidCoordinate(CoordinateError)

The a coordinate could not be parsed.

InvalidUrl(UrlError)

The r URL could not be parsed.

InvalidRelayUrl(RelayUrlError)

A relay hint URL could not be parsed.

Trait Implementations

impl Debug for LabelError

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

Formats the value using the given formatter.

impl Display for LabelError

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

Formats the value using the given formatter.

impl Error for LabelError

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.
