Enum LabelError 

#[non_exhaustive]
pub enum LabelError {
    OriginSystem,
    UnknownCategory {
        code: String,
    },
    CategoryTwice {
        code: String,
    },
    OriginKey,
    Empty {
        key: String,
    },
    Label {
        key: String,
        source: LabelCodeError,
    },
}

Why a label policy is refused.

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.

OriginSystem

The origin system is no absolute URI, or it holds a |.

UnknownCategory

A category key is neither a priority category nor a national one the category map declares.

Fields

code: String

The code.

CategoryTwice

Two category keys name the same category.

Fields

code: String

The second key.

OriginKey

An origin key is empty or holds a control character.

Empty

A key declares no label.

Fields

key: String

The key: categories.<code> or origins.<endpoint>.

Label

A key declares a label that is refused.

Fields

key: String

The key: categories.<code> or origins.<endpoint>.

Trait Implementations

impl Clone for LabelError

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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 Eq for LabelError

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.

impl PartialEq for LabelError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
