Enum FoldState 

#[non_exhaustive]
pub enum FoldState {
    Init,
    Collection,
}

The state of the fold operation

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Init

Initializing state

Collection

Collection has started
