      • hasWellKnownRegex

        boolean hasWellKnownRegex()
         `well_known_regex` specifies a common well-known pattern
 defined as a regex. If the field value doesn't match the well-known
 regex, an error message will be generated.

 ```proto
 message MyString {
 // value must be a valid HTTP header value
 string value = 1 [(buf.validate.field).string.well_known_regex = 2];
 }
 ```

      • hasStrict

        boolean hasStrict()
         This applies to regexes `HTTP_HEADER_NAME` and `HTTP_HEADER_VALUE` to
 enable strict header validation. By default, this is true, and HTTP header
 validations are [RFC-compliant](https://tools.ietf.org/html/rfc7230#section-3). Setting to false will enable looser
 validations that only disallow `\r\n\0` characters, which can be used to
 bypass header matching rules.

 ```proto
 message MyString {
 // The field `value` must have be a valid HTTP headers, but not enforced with strict rules.
 string value = 1 [(buf.validate.field).string.strict = false];
 }
 ```
        optional bool strict = 25;
        Returns:
        Whether the strict field is set.
