Enum Capability 

#[non_exhaustive]
pub enum Capability {
    Background,
    Unknown,
}

A node-enforced capability, granted by the user once per app.

A node that implements capabilities refuses one until the user has granted it, and remembers the answer per app, so the user is asked once. How a node identifies an app is the node’s business, not part of this format.

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.

Background

Run without an open app: receive lifecycle events. Required by any manifest that lists a lifecycle kind (the macro enforces it).

Unknown

A name this stdlib does not know, written by a newer one. Readers ignore it. The macro never writes it; re-serializing a manifest read from a newer stdlib does (as "unknown").
