Struct JournalCapabilities 

pub struct JournalCapabilities {
    pub fencing: bool,
    pub state_in_append: bool,
}

What a journal store supports beyond compare-and-set, read before relying on it.

Fields

fencing: bool

The store enforces fencing tokens. A store without fencing rejects an append that carries a token with AppendError::Unsupported instead of ignoring it.

state_in_append: bool

The store commits a StateDelta in the same transaction as the entries.
