Enum DownloadStatus 

pub enum DownloadStatus {
    Downloaded,
    Paywall,
    Failed,
}

Outcome of a paper download attempt. Persisted on papers.download_status.

Downloaded means the adapter classified the fetched bytes as full content. Paywall means we got bytes but they’re an HTML stub / abstract / paywall page — file exists but doesn’t contain the paper. Failed means the download itself errored (network, 404, etc.).

Implementations

impl DownloadStatus

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

SQL-friendly string used in the download_status text column.

pub fn parse(s: &str) -> Option<Self>

Inverse of as_str. Returns None for unknown values so a stale row from a future schema doesn’t crash the loader.
