Enum Fidelity 

pub enum Fidelity {
    ByteLossless,
    ValueLossless,
    Semantic,
}

How faithfully a reconstruction reproduces its source.

One vocabulary for every surface that has to state what it gave up. It was introduced for session ARTIFACTS (harness.v1.sessions.export reports a level plus a named residue list); session LOADS report the same pair, because a read-only VIEW of a session is allowed to settle for Fidelity::Semantic where a continuation is not (see crate::Session::load_with_fidelity).

Variants

ByteLossless

The reconstruction reproduces the source bytes exactly.

ValueLossless

Every value survives; only the container bytes were re-synthesized.

Semantic

Meaning survives; the named residue says exactly what did not.

Implementations

impl Fidelity

pub fn tolerates_residue(self) -> bool

Whether this level tolerates named loss.

Only Fidelity::Semantic does — every stricter level must fail loudly instead of degrading, which is what keeps continuation, transfer and export guarantees intact.
