Duration rules ​

DurationRules describe the constraints applied exclusively to the google.protobuf.Duration well-known type.

const ​

const dictates that the field must match the specified value of the google.protobuf.Duration type exactly. If the field's value deviates from the specified value, an error message will be generated.

duration.const example

proto
message MyDuration {
  // value must equal 5s
  google.protobuf.Duration value = 1 [(buf.validate.field).duration.const = "5s"];
}

lt ​

lt stipulates that the field must be less than the specified value of the google.protobuf.Duration type, exclusive. If the field's value is greater than or equal to the specified value, an error message will be generated.

duration.lt example

proto
message MyDuration {
  // value must be less than 5s
  google.protobuf.Duration value = 1 [(buf.validate.field).duration.lt = "5s"];
}

lte ​

lte indicates that the field must be less than or equal to the specified value of the google.protobuf.Duration type, inclusive. If the field's value is greater than the specified value, an error message will be generated.

duration.lte example

proto
message MyDuration {
  // value must be less than or equal to 10s
  google.protobuf.Duration value = 1 [(buf.validate.field).duration.lte = "10s"];
}

gt ​

gt requires the duration field value to be greater than the specified value (exclusive). If the value of gt is larger than a specified lt or lte, the range is reversed, and the field value must be outside the specified range. If the field value doesn't meet the required conditions, an error message is generated.

duration.gt example

proto
message MyDuration {
  // duration must be greater than 5s [duration.gt]
  google.protobuf.Duration value = 1 [(buf.validate.field).duration.gt = { seconds: 5 }];

  // duration must be greater than 5s and less than 10s [duration.gt_lt]
  google.protobuf.Duration another_value = 2 [(buf.validate.field).duration = { gt: { seconds: 5 }, lt: { seconds: 10 } }];

  // duration must be greater than 10s or less than 5s [duration.gt_lt_exclusive]
  google.protobuf.Duration other_value = 3 [(buf.validate.field).duration = { gt: { seconds: 10 }, lt: { seconds: 5 } }];
}

gte ​

gte requires the duration field value to be greater than or equal to the specified value (exclusive). If the value of gte is larger than a specified lt or lte, the range is reversed, and the field value must be outside the specified range. If the field value doesn't meet the required conditions, an error message is generated.

duration.gte example

proto
message MyDuration {
 // duration must be greater than or equal to 5s [duration.gte]
 google.protobuf.Duration value = 1 [(buf.validate.field).duration.gte = { seconds: 5 }];

 // duration must be greater than or equal to 5s and less than 10s [duration.gte_lt]
 google.protobuf.Duration another_value = 2 [(buf.validate.field).duration = { gte: { seconds: 5 }, lt: { seconds: 10 } }];

 // duration must be greater than or equal to 10s or less than 5s [duration.gte_lt_exclusive]
 google.protobuf.Duration other_value = 3 [(buf.validate.field).duration = { gte: { seconds: 10 }, lt: { seconds: 5 } }];
}

in ​

in asserts that the field must be equal to one of the specified values of the google.protobuf.Duration type. If the field's value doesn't correspond to any of the specified values, an error message will be generated.

duration.in example

proto
message MyDuration {
  // value must be in list [1s, 2s, 3s]
  google.protobuf.Duration value = 1 [(buf.validate.field).duration.in = ["1s", "2s", "3s"]];
}

not_in ​

not_in denotes that the field must not be equal to any of the specified values of the google.protobuf.Duration type. If the field's value matches any of these values, an error message will be generated.

duration.not_in example

proto
message MyDuration {
  // value must not be in list [1s, 2s, 3s]
  google.protobuf.Duration value = 1 [(buf.validate.field).duration.not_in = ["1s", "2s", "3s"]];
}

example ​

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

duration.example example

proto
message MyDuration {
  google.protobuf.Duration value = 1 [
    (buf.validate.field).duration.example = { seconds: 1 },
    (buf.validate.field).duration.example = { seconds: 2 },
  ];
}
