use crate::OptionValue;

/// The structure of a custom Cel rule used to define validation logic with protovalidate.
/// The id should be a unique identifier for the given rule, which will appear in error messages.
/// The message is the error message that will show up in case of validation failure.
/// The expression is a [Cel](https://cel.dev/) expression that will be executed on validation by protovalidate-compatible libraries such as [protocheck](https://github.com/Rick-Phoenix/protocheck) (for rust) or [protovalidate-es](https://github.com/bufbuild/protovalidate-es) (for javascript).
/// <br/>
/// You can use the [`cel_rule`](crate::cel_rule) macro to build them with a shorter syntax.
