Struct TimestampRules

pub struct TimestampRules {
    pub const: Option<Timestamp>,
    pub within: Option<Duration>,
    pub example: Vec<Timestamp>,
    pub less_than: Option<LessThan>,
    pub greater_than: Option<GreaterThan>,
}

TimestampRules describe the rules applied exclusively to the google.protobuf.Timestamp well-known type.

Fields

const: Option<Timestamp>

const dictates that this field, of the google.protobuf.Timestamp type, must exactly match the specified value. If the field value doesn’t correspond to the specified timestamp, an error message will be generated.

message MyTimestamp {
   // value must equal 2023-05-03T10:00:00Z
   google.protobuf.Timestamp created_at = 1 \[(buf.validate.field).timestamp.const = {seconds: 1727998800}\];
}

within: Option<Duration>

within specifies that this field, of the google.protobuf.Timestamp type, must be within the specified duration of the current time. If the field value isn’t within the duration, an error message is generated.

message MyTimestamp {
   // value must be within 1 hour of now
   google.protobuf.Timestamp created_at = 1 \[(buf.validate.field).timestamp.within = {seconds: 3600}\];
}

example: Vec<Timestamp>

example specifies values that the field may have. These values SHOULD conform to other rules. example values will not impact validation but may be used as helpful guidance on how to populate the given field.

message MyTimestamp {
   google.protobuf.Timestamp value = 1 [
     (buf.validate.field).timestamp.example = { seconds: 1672444800 },
     (buf.validate.field).timestamp.example = { seconds: 1672531200 },
   ];
}

less_than: Option<LessThan>

greater_than: Option<GreaterThan>

Trait Implementations

impl Clone for TimestampRules

fn clone(&self) -> TimestampRules

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimestampRules

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

Formats the value using the given formatter.

impl Default for TimestampRules

fn default() -> Self

Returns the “default value” for a type.

impl Message for TimestampRules

fn encoded_len(&self) -> usize

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

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

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

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for TimestampRules

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