Fixed64 rules ​

Fixed64Rules describes the constraints applied to fixed64 values.

const ​

const requires the field value to exactly match the specified value. If the field value doesn't match, an error message is generated.

fixed64.const example

proto
message MyFixed64 {
  // value must equal 42
  fixed64 value = 1 [(buf.validate.field).fixed64.const = 42];
}

lt ​

lt requires the field value to be less than the specified value (field < value). If the field value is equal to or greater than the specified value, an error message is generated.

fixed64.lt example

proto
message MyFixed64 {
  // value must be less than 10
  fixed64 value = 1 [(buf.validate.field).fixed64.lt = 10];
}

lte ​

lte requires the field value to be less than or equal to the specified value (field <= value). If the field value is greater than the specified value, an error message is generated.

fixed64.lte example

proto
message MyFixed64 {
  // value must be less than or equal to 10
  fixed64 value = 1 [(buf.validate.field).fixed64.lte = 10];
}

gt ​

gt requires the 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.

fixed64.gt example

proto
message MyFixed64 {
  // value must be greater than 5 [fixed64.gt]
  fixed64 value = 1 [(buf.validate.field).fixed64.gt = 5];

  // value must be greater than 5 and less than 10 [fixed64.gt_lt]
  fixed64 other_value = 2 [(buf.validate.field).fixed64 = { gt: 5, lt: 10 }];

  // value must be greater than 10 or less than 5 [fixed64.gt_lt_exclusive]
  fixed64 another_value = 3 [(buf.validate.field).fixed64 = { gt: 10, lt: 5 }];
}

gte ​

gte requires the 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.

fixed64.gte example

proto
message MyFixed64 {
  // value must be greater than or equal to 5 [fixed64.gte]
  fixed64 value = 1 [(buf.validate.field).fixed64.gte = 5];

  // value must be greater than or equal to 5 and less than 10 [fixed64.gte_lt]
  fixed64 other_value = 2 [(buf.validate.field).fixed64 = { gte: 5, lt: 10 }];

  // value must be greater than or equal to 10 or less than 5 [fixed64.gte_lt_exclusive]
  fixed64 another_value = 3 [(buf.validate.field).fixed64 = { gte: 10, lt: 5 }];
}

in ​

in requires the field value to be equal to one of the specified values. If the field value isn't one of the specified values, an error message is generated.

fixed64.in example

proto
message MyFixed64 {
  // value must be in list [1, 2, 3]
  repeated fixed64 value = 1 (buf.validate.field).fixed64 = { in: [1, 2, 3] };
}

not_in ​

not_in requires the field value to not be equal to any of the specified values. If the field value is one of the specified values, an error message is generated.

fixed64.not_in example

proto
message MyFixed64 {
  // value must not be in list [1, 2, 3]
  repeated fixed64 value = 1 (buf.validate.field).fixed64 = { not_in: [1, 2, 3] };
}

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.

fixed64.example example

proto
message MyFixed64 {
  fixed64 value = 1 [
    (buf.validate.field).fixed64.example = 1,
    (buf.validate.field).fixed64.example = 2
  ];
}
