Enum LabelError 

pub enum LabelError {
    Empty,
    TooLong,
    InvalidStart,
    InvalidEnd,
    InvalidChar(char),
}

Errors that can occur when constructing a Label.

Variants

Empty

The input string is empty.

TooLong

The input exceeds 63 characters.

InvalidStart

The first character is not an ASCII lowercase letter.

InvalidEnd

The last character is not alphanumeric.

InvalidChar(char)

The input contains a character that is not lowercase alphanumeric or -.

Trait Implementations

impl Clone for LabelError

fn clone(&self) -> LabelError

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 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 From<LabelError> for UidParseError

fn from(source: LabelError) -> Self

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.
