Enum DerivationKind 

#[non_exhaustive]
pub enum DerivationKind {
    Created,
    Shared,
    Other(String),
}

How an upstream subscription came to serve a downstream one.

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.

Created

A new upstream subscription was created to satisfy downstream subs.

Shared

An existing upstream subscription now also serves an additional downstream sub — subscription fan-in.

Other(String)

A kind this version of the crate does not know, kept verbatim.
