Struct StoredUnit 

pub struct StoredUnit {
    pub fdata_offset: u64,
    pub payload: UnitPayload,
}

One stored unit: what a splitter emits, and what becomes one index row.

fdata_offset is where this unit’s bytes belong inside the reconstructed file, which is what makes a MIXED entry expressible: the units of one entry need not all be of the same kind, they only need to tile the file.

Fields

fdata_offset: u64

Offset of this unit’s bytes within the reconstructed file.

payload: UnitPayload
