Enum ContentState 

pub enum ContentState {
    Current(ContentInfo),
    Stale(StaleReason),
}

What a content sidecar beside a snapshot holds.

Variants

Current(ContentInfo)

A sidecar this build reads.

Stale(StaleReason)

One of fdu’s sidecars that this build cannot serve: another format or engine, or a header this build cannot read.

Implementations

impl ContentState

pub const LABELS: [&'static str; 2]

Every label a content sidecar’s state can carry, in declaration order.

The two a sidecar can be, which is narrower than CacheState::LABELS: a sidecar is never leftover, unrecognized, or absent under its own status, because it is reported only where one was found beside a snapshot.

pub fn label(&self) -> &'static str

The label machine output carries, one of Self::LABELS.
