Enum WellKnown 

pub enum WellKnown {
    Ip(bool),
    Ipv4(bool),
    Ipv6(bool),
}

WellKnown rules provide advanced rules against common byte patterns

Variants

Ip(bool)

ip ensures that the field value is a valid IP address (v4 or v6) in byte format. If the field value doesn’t meet this rule, an error message is generated.

message MyBytes {
   // value must be a valid IP address
   optional bytes value = 1 \[(buf.validate.field).bytes.ip = true\];
}

Ipv4(bool)

ipv4 ensures that the field value is a valid IPv4 address in byte format. If the field value doesn’t meet this rule, an error message is generated.

message MyBytes {
   // value must be a valid IPv4 address
   optional bytes value = 1 \[(buf.validate.field).bytes.ipv4 = true\];
}

Ipv6(bool)

ipv6 ensures that the field value is a valid IPv6 address in byte format. If the field value doesn’t meet this rule, an error message is generated.

message MyBytes {
   // value must be a valid IPv6 address
   optional bytes value = 1 \[(buf.validate.field).bytes.ipv6 = true\];
}

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 Debug for WellKnown

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

Formats the value using the given formatter.

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.

impl Copy for WellKnown
