Enum IdSource 

pub enum IdSource {
    Provider,
    Derived(&'static [&'static str]),
}

Whose uniqueness an identifier rests on.

One question, asked of every identifier kasapay hands back: did the provider give us this, or did we make it up? A caller writing an identifier into a unique index — so a second webhook delivery collides instead of shipping twice — is relying on somebody’s guarantee, and the two answers are worth very different things.

Exhaustive on purpose. There is no third answer, and an adapter that adds one has invented a guarantee nobody made.

Variants

Provider

The provider issued it, and it is unique because they say so.

Derived(&'static [&'static str])

kasapay composed it out of the named fields, because the provider issues none of its own. It is unique exactly as far as those fields are.
