Enum RegenerationFiles 

pub enum RegenerationFiles {
    Single(Vec<String>),
    Variants(Vec<VariantFileSet>),
}

Complete ordered input membership for a regeneration operation. The case must match the result’s generation mode. Synchronous methods borrow this value; async methods consume it.

Variants

Single(Vec<String>)

Single-design font inputs, in the order a fresh generation would use.

Variants(Vec<VariantFileSet>)

Complete file sets for every configured variant, each named exactly once. The order of these entries does not change configured design order. Paths can be shared between designs; each design’s file list independently determines its membership and order.
