Struct ReducerEvent 

#[non_exhaustive]
pub struct ReducerEvent<R> {
    pub timestamp: Timestamp,
    pub status: Status,
    pub caller_identity: Identity,
    pub caller_connection_id: Option<ConnectionId>,
    pub energy_consumed: Option<u128>,
    pub reducer: R,
}

A state change due to a reducer, which may or may not have committed successfully.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

timestamp: Timestamp

The time at which the reducer was invoked.

status: Status

Whether the reducer committed, was aborted due to insufficient energy, or failed with an error message.

caller_identity: Identity

The Identity of the SpacetimeDB actor which invoked the reducer.

caller_connection_id: Option<ConnectionId>

The ConnectionId of the SpacetimeDB actor which invoked the reducer, or None for scheduled reducers.

energy_consumed: Option<u128>

The amount of energy consumed by the reducer run, in eV. (Not literal eV, but our SpacetimeDB energy unit eV.)

May be None if the module is configured not to broadcast energy consumed.

reducer: R

The Reducer enum defined by the module_bindings, which encodes which reducer ran and its arguments.
