Enum UsernameError

#[non_exhaustive]
pub enum UsernameError {
    ContainsColon,
    InvalidCharacter,
    InvalidPercentEncoding,
}

An error representing an invalid username component.

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.

ContainsColon

The username contained a ':' which is only to be used as a delimiter between the username and password. This variant can only happen when trying to directly parse a username from a byte source.

InvalidCharacter

The username contained an invalid character.

InvalidPercentEncoding

The username contained an invalid percent encoding (e.g. "%ZZ").

Trait Implementations

impl Clone for UsernameError

fn clone(&self) -> UsernameError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UsernameError

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

Formats the value using the given formatter.

impl Display for UsernameError

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

Formats the value using the given formatter.

impl Error for UsernameError

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<Infallible> for UsernameError

fn from(_: Infallible) -> Self

Converts to this type from the input type.

impl From<UsernameError> for AuthorityError

fn from(value: UsernameError) -> Self

Converts to this type from the input type.

impl Hash for UsernameError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UsernameError

fn eq(&self, other: &UsernameError) -> 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.
