public final class Constraint extends com.google.protobuf.GeneratedMessageV3 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;
 }
 ```
