Enum ContentHint 

pub enum ContentHint {
    Unknown,
    AlreadyCompressed,
    Compressible,
}

The probe itself, re-exported so znippy_common::precompressed::* keeps naming exactly what it always named. These are ldeflate’s items, not copies of them — breaking one there breaks every znippy caller, which is the point of the move. What a caller already knows about its content, if anything.

The hint is honoured in both directions: Compressible is never vetoed by a probe, so a caller who knows better than the magic bytes wins.

Variants

Unknown

Nothing known — probe the bytes.

AlreadyCompressed

Caller asserts this is already compressed. Store it, do not probe.

Compressible

Caller asserts this is worth compressing. Compress it, do not probe.
