Enum KeyLabelError 

pub enum KeyLabelError {
    Empty,
    TooLong,
    InvalidByte,
}

Stable key-label validation failures.

Variants

Empty

Key labels must contain at least one byte.

TooLong

Key labels exceeded the bounded length policy.

InvalidByte

Key labels contained a byte outside the allowlist.

Trait Implementations

impl Clone for KeyLabelError

fn clone(&self) -> Self

impl Copy for KeyLabelError

impl Debug for KeyLabelError

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

Formats the value using the given formatter.

impl Eq for KeyLabelError

impl Error for KeyLabelError

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 KeyLabelError

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

Equality operator ==.

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

Inequality operator !=.
