Trait ConfigField 

pub trait ConfigField {
    // Required method
    fn merge_field(
        &mut self,
        field_name: &str,
        other: Self,
    ) -> Result<(), Error>;
}

Trait for merging a single config field. The flowey_config! macro calls ConfigField::merge_field on each field during config merging.

Implemented for:

• Option<T>: first setter wins, subsequent must agree (PartialEq)
• BTreeMap<K, V>: per-key merge, each key’s value must agree

Required Methods

fn merge_field(&mut self, field_name: &str, other: Self) -> Result<(), Error>

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.
