Struct EventLogEntry

pub struct EventLogEntry {
    pub kind: EventKind,
    pub module: Option<(ModuleKind, ModuleInstanceId)>,
    pub(crate) ts_usecs: u64,
    pub payload: Vec<u8>,
}

Fields

kind: EventKind

Type/kind of the event

Any part of the client is free to self-allocate identifier, denoting a certain kind of an event. Notably one event kind have multiple instances. E.g. “successful wallet deposit” can be an event kind, and it can happen multiple times with different payloads.

module: Option<(ModuleKind, ModuleInstanceId)>

To prevent accidental conflicts between kinds, a module kind the given event kind belong is used as well.

Note: the meaning of this field is mostly about which part of the code defines this event kind. Oftentime a core (non-module)-defined event will refer in some way to a module. It should use a separate module_id field in the payload, instead of this field.

ts_usecs: u64

Timestamp in microseconds after unix epoch

payload: Vec<u8>

Event-kind specific payload, typically encoded as a json string for flexibility.

Trait Implementations
