Enum RangeOutcome 

pub enum RangeOutcome {
    Ignore,
    Unsatisfiable,
    Satisfiable(u64, u64),
}

The outcome of interpreting a Range header against a file of size bytes.

RFC 9110 §14.2 requires two different failure shapes to produce two different responses: an unrecognised range unit, or a syntactically invalid bytes spec, must be ignored — served as the whole file, 200 — while only a well-formed bytes range that names bytes the file does not have is “not satisfiable” (416). Collapsing both into one Option::None, as an earlier version of this function did, served 416 for Range: items=0-4, which the RFC forbids.

Variants

Ignore

No usable range: fall through to serving the whole file, exactly as if Range had not been sent at all.

Unsatisfiable

A well-formed bytes range outside the file’s current length.

Satisfiable(u64, u64)

A well-formed, in-bounds range: inclusive (start, end).
