Enum Fidelity 

pub enum Fidelity {
    Lossless,
    Degraded,
    Unrepresentable,
}

How faithfully the markdown projection carries an island: the closed view over Loss, and what a consumer switches on.

The KnownIslandType twin, one axis over, and exhaustive for the same reason: a consumer laddering on fidelity has no safe fallthrough for a rung it does not know, so a new rung is a major bump rather than a silent gap.

Variants

Lossless

Round-trips identically.

Degraded

Round-trips visibly, not identically.

Unrepresentable

No markdown encoding, and where an uninterpretable class lands.

Implementations

impl Fidelity

pub const ALL: &'static [Fidelity]

Every level, faithful first. The one enumeration point, so a reader that needs the closed set whole (the WASM surface’s class union, say) asks rather than re-spelling it.

pub const fn as_str(self) -> &'static str

The wire class naming this level: the one place a class is spelled, which Loss’s consts and Fidelity::parse both read.

pub fn parse(class: &str) -> Option<Fidelity>

Parse a wire class into the closed view. None is the open-set escape hatch (an uninterpretable class), which Loss::fidelity reads as Unrepresentable.
