Trait ActionParams 

pub trait ActionParams: Action {
    // Required method
    fn params(&self) -> String;
}

Trait for getting action parameters without the variant name.

Auto-implemented by #[derive(Action)]. Returns just the field values as a string, suitable for display in action logs where the action name is already shown separately.

Example

#[derive(Action, Clone, Debug)]
enum MyAction {
    SetFilter { query: String, limit: usize },
    Tick,
}

let action = MyAction::SetFilter { query: "foo".into(), limit: 10 };
assert_eq!(action.name(), "SetFilter");
assert_eq!(action.params(), r#""foo", 10"#);

let tick = MyAction::Tick;
assert_eq!(tick.params(), "");

Required Methods

fn params(&self) -> String

Get just the action parameters as a string (no variant name)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
