Enum servo_url::Host

pub enum Host<S = String> {
    Domain(S),
    Ipv4(Ipv4Addr),
    Ipv6(Ipv6Addr),
}

The host name of an URL.

Variants

Domain(S)

A DNS domain name, as ‘.’ dot-separated labels. Non-ASCII labels are encoded in punycode per IDNA if this is the host of a special URL, or percent encoded for non-special URLs. Hosts for non-special URLs are also called opaque hosts.

Ipv4(Ipv4Addr)

An IPv4 address. Url::host_str returns the serialization of this address, as four decimal integers separated by . dots.

Ipv6(Ipv6Addr)

An IPv6 address. Url::host_str returns the serialization of that address between [ and ] brackets, in the format per RFC 5952 A Recommendation for IPv6 Address Text Representation: lowercase hexadecimal with maximal :: compression.

Implementations

impl<'a> Host<&'a str>

pub fn to_owned(&self) -> Host<String>

Return a copy of self that owns an allocated String but does not borrow an &Url.

impl Host<String>

pub fn parse(input: &str) -> Result<Host<String>, ParseError>

Parse a host: either an IPv6 address in [] square brackets, or a domain.

Trait Implementations

impl<S> Clone for Host<S>where S: Clone,

fn clone(&self) -> Host<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S> Debug for Host<S>where S: Debug,

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

Formats the value using the given formatter.

impl<'de, S> Deserialize<'de> for Host<S>where S: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D ) -> Result<Host<S>, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S> Display for Host<S>where S: AsRef<str>,

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

Formats the value using the given formatter.

impl<S> Hash for Host<S>where S: Hash,

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

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 MallocSizeOf for Host<String>

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<S> Ord for Host<S>where S: Ord,

fn cmp(&self, other: &Host<S>) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl<S, T> PartialEq<Host<T>> for Host<S>where S: PartialEq<T>,

fn eq(&self, other: &Host<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<S> Serialize for Host<S>where S: Serialize,

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<S> Eq for Host<S>where S: Eq,
