Enum WriteSupport 

pub enum WriteSupport {
    Supported,
    Unsupported,
}

Whether a source can be written through at all.

Deliberately its own enum rather than a reuse of Support: that one says whether a source applies a predicate itself, and the engine compensates for an Unsupported there by narrowing a wider result. There is no compensating for a destination that cannot be written — the copy is refused, naming the source and the plugin behind it — so conflating the two would invite an engine-side workaround for a case that has none.

Variants

Supported

The source creates and updates items through its own write interface.

Unsupported

The source has no write side; a copy naming it as a destination is refused.
