Enum DomainSegmentError 

pub enum DomainSegmentError {
    IllegalHyphen(usize),
    InvalidCharacter(char),
    TooLong(usize),
    EmptyString,
    NonStandaloneWildcard,
}

Produced when attempting to construct a DomainSegment from an invalid string.

Variants

IllegalHyphen(usize)

Domain name segments can contain hyphens, but crucially:

• Not at the beginning of a segment.
• Not at the end of a segment.
• Not at the 3rd and 4th position simultaneously (used for Punycode encoding)

InvalidCharacter(char)

Segment contains invalid character.

TooLong(usize)

Domain segment is longer than the permitted 63 characters.

EmptyString

Domain segment is empty.

NonStandaloneWildcard

Domain segments can be wildcards, but must then only contain the wildcard.

Trait Implementations

impl Clone for DomainSegmentError

fn clone(&self) -> DomainSegmentError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DomainSegmentError

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

Formats the value using the given formatter.

impl Display for DomainSegmentError

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

Formats the value using the given formatter.

impl Error for DomainSegmentError

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<DomainSegmentError> for FullyQualifiedDomainNameError

fn from(source: DomainSegmentError) -> Self

Converts to this type from the input type.

impl From<DomainSegmentError> for PartiallyQualifiedDomainNameError

fn from(source: DomainSegmentError) -> Self

Converts to this type from the input type.

impl Ord for DomainSegmentError

fn cmp(&self, other: &DomainSegmentError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DomainSegmentError

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

impl PartialOrd for DomainSegmentError

fn partial_cmp(&self, other: &DomainSegmentError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
