    extends com.google.protobuf.GeneratedMessage
    implements ConstraintOrBuilder
     `Constraint` represents a validation rule written in the Common Expression
     Language (CEL) syntax. Each Constraint includes a unique identifier, an
     optional error message, and the CEL expression to evaluate. For more
     information on CEL, [see our documentation](https://github.com/bufbuild/protovalidate/blob/main/docs/cel.md).
    
     ```proto
     message Foo {
     option (buf.validate.message).cel = {
     id: "foo.bar"
     message: "bar must be greater than 0"
     expression: "this.bar > 0"
     };
     int32 bar = 1;
     }
     ```
