Enum Event 

pub enum Event {
    State(Value),
    Log {
        level: &'static str,
        text: String,
    },
}

What the engine tells the UI, through the sink given to spawn.

The sink is called on the engine thread for Event::State, and on whatever thread logged for Event::Log, so it must be cheap and must not call Engine::query and wait.

Variants

State(Value)

The whole view state, sent only when it differs from the last one.

Log

One log line at or above INFO.

Fields

level: &'static str

The level’s name: TRACE, DEBUG, INFO, WARN or ERROR.

text: String

The message, without the level.
