Struct Tally 

#[non_exhaustive]
pub struct Tally {
    pub count: u64,
    pub unmodeled_fields: BTreeMap<String, u64>,
}

A tally for one discriminant value.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

count: u64

How many times it occurred.

unmodeled_fields: BTreeMap<String, u64>

Field keys seen in extra (fields we didn’t model), with counts.
