Enum AssetSource 

#[non_exhaustive]
pub enum AssetSource {
    Vendored(&'static [u8]),
    External {
        hint: &'static str,
    },
    Download {
        files: &'static [DownloadFile],
    },
    PinnedArchive {
        archives: &'static [PinnedArchive],
    },
}

Where an asset comes from.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Vendored(&'static [u8])

Bytes compiled into this binary, installed as a single file.

External

A directory the operator provisions, which Roteiro verifies and pins but never fetches. hint is the exact command that obtains it.

Fields

hint: &'static str

What to run to obtain it, quoted verbatim in every error.

Download

A set of files downloaded by URL into one directory, digest-pinned at provisioning time.

Downloading happens only in provision_with, and only with a fetcher the caller supplied. There is no compile-time digest because the upstream files are republished continuously — OSV rebuilds its per-ecosystem databases daily — so what is pinned is the snapshot this machine provisioned, recorded in InstalledAsset::digest and re-checked on every run. That is the same pin the RustSec checkout gets, and it is the one that can actually be honoured.

Fields

files: &'static [DownloadFile]

Each file’s path relative to the asset directory, and where it comes from. Order is preserved so prefetch reports progress in a stable sequence.

PinnedArchive

A single published release artifact with a compile-time SHA-256, installed as one file and selected by host platform.

Verified in this crate, before installation and again by build.rs before anything is built against it — so neither a lying fetcher nor a redirected URL can substitute different bytes. See crate::runtime_pins for what is pinned and why it has to be.

Fields

archives: &'static [PinnedArchive]

One entry per supported host platform. A host not listed here cannot be provisioned, and is told which platforms are.
