Enum MetaValue 

pub enum MetaValue {
    Str(String),
    I64(i64),
    F64(f64),
    Bool(bool),
    Bytes(Vec<u8>),
}

One typed metadata value. Round-trips through serde and through the Arrow columns of meta_schema — the on-disk form is columnar (one nullable column per variant plus a discriminant), so the section stays directly queryable by DuckDB/Polars, exactly like the rest of znippy’s index layer.

Variants

Str(String)

I64(i64)

F64(f64)

Bool(bool)

Bytes(Vec<u8>)

Opaque bytes — e.g. dwarves’ build-thing wasm module, or a digest.
