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.

Io

Reading the toml file failed.

Fields

path: PathBuf

source: Error

Parse

The toml body did not parse.

Fields

path: PathBuf

message: String

ReservedNamespace

[labels] declared the reserved lex namespace. The lex.* label space is owned by the core and ships compiled-in; re-declaring it would silently shadow core built-ins.

TapAndUri

Table form had both tap and uri set. They’re mutually exclusive — pick one.

EmptyTable

Table form had neither tap nor uri set.

RevWithExplicitFragment

Both the explicit uri (with a #fragment) and a rev field are set. Either is meaningful but together they’re ambiguous — pick one.

Fields

uri: String

rev: String

ViaOnNonTemplateScheme

via was declared on a spec whose URI scheme is not a URL template (github: / gitlab:). The transport is already fully determined by the scheme, so via would silently no-op — reject it instead.

Fields

uri: String

Trait Implementations

impl Debug for LabelsConfigError

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

Formats the value using the given formatter.

impl Display for LabelsConfigError

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

Formats the value using the given formatter.

impl Error for LabelsConfigError

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.
