Struct LabelError

#[non_exhaustive]
pub struct LabelError { /* private fields */ }

Errors related to labels.

Implementations

impl LabelError

pub fn new(label: &str) -> Self

Create a new LabelError for the given invalid label.

pub fn label(&self) -> &str

The invalid label string (if available).

Trait Implementations

impl Clone for LabelError

fn clone(&self) -> LabelError

Returns a copy 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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for LabelError

Available on crate feature std only.

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<LabelError> for Error

fn from(err: LabelError) -> Error

Converts to this type from the input type.

impl PartialEq for LabelError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
