Enum HostError

#[non_exhaustive]
pub enum HostError {
    AddressMechanismNotSupported,
    InvalidIPv4OrRegisteredNameCharacter,
    InvalidIPv6Character,
    InvalidIPv6Format,
    InvalidIPvFutureCharacter,
}

An error representing an invalid host.

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.

AddressMechanismNotSupported

The syntax for a future IP literal was used and is not currently supported.

InvalidIPv4OrRegisteredNameCharacter

An invalid character for an IPv4 address or registered name was used. Due to the ambiguity of the grammar, it is not possible to say which. It is also possible that all the characters were valid, but there was an invalid percent encoding (e.g. "%ZZ").

InvalidIPv6Character

The syntax for an IPv6 literal was used (i.e. "[...]"), but it contained an invalid IPv6 character.

InvalidIPv6Format

The syntax for an IPv6 literal was used (i.e. "[...]") and all of the characters were valid IPv6 characters. However, the format of the literal was invalid.

InvalidIPvFutureCharacter

The syntax for a future IP literal was used (i.e. "[v*...]" where "*" is a hexadecimal digit), but it contained an invalid character.

Trait Implementations

impl Clone for HostError

fn clone(&self) -> HostError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HostError

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

Formats the value using the given formatter.

impl Display for HostError

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

Formats the value using the given formatter.

impl Error for HostError

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<HostError> for AuthorityError

fn from(value: HostError) -> Self

Converts to this type from the input type.

impl From<Infallible> for HostError

fn from(_: Infallible) -> Self

Converts to this type from the input type.

impl Hash for HostError

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 HostError

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