AnyOperation

p2panda_core::operation

Struct AnyOperation 

Source 
pub struct AnyOperation {
    pub hash: Hash,
    pub header: AnyHeader,
    pub body: Option<Body>,
}
Expand description

Combined AnyHeader, Body and operation Hash (Operation Id).

§Extensions

AnyOperation does not know the concrete extensions type. On this level it is only concerned with the validity and integrity of the append-only log type itself which is enough for most low-level protocols, such as the sync protocol.

Applications usually want to attach custom extensions to the operation, if you need to know the type you can easily convert from AnyOperation to Operation with an explicit E extensions type.

Trait Implementations§

Source§

impl Chain<Hash> for AnyOperation

Pointer at previous entry in log which gives us the integrity guarantee of the “hash chain”. The first entry in a log returns None.
Source§

fn seq_num(&self) -> SeqNum

Sequence numbers are helpful to fastly detect forks and use the much faster and optimized diffing strategy when the local log is not forked.
