Enum WellKnown 

pub enum WellKnown {
    Email(bool),
    Hostname(bool),
    Ip(bool),
    Ipv4(bool),
    Ipv6(bool),
    Uri(bool),
    UriRef(bool),
    Address(bool),
    Uuid(bool),

}

WellKnown rules provide advanced constraints against common string patterns

Variants

Email(bool)

Email specifies that the field must be a valid email address as defined by RFC 5322

Hostname(bool)

Hostname specifies that the field must be a valid hostname as defined by RFC 1034. This constraint does not support internationalized domain names (IDNs).

Ip(bool)

Ip specifies that the field must be a valid IP (v4 or v6) address. Valid IPv6 addresses should not include surrounding square brackets.

Ipv4(bool)

Ipv4 specifies that the field must be a valid IPv4 address.

Ipv6(bool)

Ipv6 specifies that the field must be a valid IPv6 address. Valid IPv6 addresses should not include surrounding square brackets.

Uri(bool)

Uri specifies that the field must be a valid, absolute URI as defined by RFC 3986

UriRef(bool)

UriRef specifies that the field must be a valid URI as defined by RFC 3986 and may be relative or absolute.

Address(bool)

Address specifies that the field must be either a valid hostname as defined by RFC 1034 (which does not support internationalized domain names or IDNs), or it can be a valid IP (v4 or v6).

Uuid(bool)

Uuid specifies that the field must be a valid UUID as defined by RFC 4122

WellKnownRegex(i32)

WellKnownRegex specifies a common well known pattern defined as a regex.

Implementations

impl WellKnown

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<WellKnown>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for WellKnown

fn clone(&self) -> WellKnown

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for WellKnown

impl Debug for WellKnown

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

Formats the value using the given formatter.

impl Eq for WellKnown

impl Hash for WellKnown

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 WellKnown

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