Enum Source 

pub enum Source {
    Bundled,
    Ours {
        repo: &'static str,
        rev: &'static str,
    },
    Upstream {
        repo: &'static str,
        license: &'static str,
        rev: &'static str,
    },
    Mirrored {
        ours: &'static str,
        upstream: &'static str,
        license: &'static str,
        rev: &'static str,
    },
}

Where a set of weights comes from, and what we are permitted to do with it.

An earlier version of this enum forbade mirroring third-party weights on principle. That was the wrong rule: every model this engine uses turns out to be permissively licensed (Apache-2.0 or MIT), so mirroring is allowed. The obligations that do bind are attribution, carrying the licence text, and stating modifications — none of which is satisfied by simply refusing to host a copy.

The more important protection is the pinned revision. A mirror without a pin still drifts when we refresh it; a pin without a mirror still breaks when upstream deletes the repo. Both, where permitted.

Variants

Bundled

Compiled into this crate. Small, ours, offline by construction.

Ours

Trained by this project and published to our own model repository.

Fields

repo: &'static str

rev: &'static str

Upstream

Someone else’s weights, fetched from the repository that published them.

Fields

repo: &'static str

license: &'static str

rev: &'static str

Mirrored

Someone else’s weights that we also host, as the licence permits, so a build does not depend on an upstream repository staying where it is. upstream is retained because attribution does not transfer.

Fields

ours: &'static str

upstream: &'static str

license: &'static str

rev: &'static str

Implementations

impl Source

pub fn license(&self) -> Option<&'static str>

The licence a redistribution must carry, if this is not our own work.

pub fn attribution(&self) -> Option<&'static str>

Who to credit.

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

The revision this build expects. Pinning is what makes a fetch reproducible.

pub fn fetch_repo(&self) -> Option<&'static str>

Where to fetch from, preferring our mirror when one exists.
