Trait FieldRewriteResult 

pub trait FieldRewriteResult {
    // Required method
    fn into_field_rewrite_result(self) -> Option<FieldValue>;
}

Converts a field rewrite handler result into an optional replacement.

Returning a plain value replaces the field. Returning Option<T> allows a handler to keep the original field by returning None.

Converts this handler result into an optional FieldValue.
