Struct Engine 

pub struct Engine {
    tx: Sender<Msg>,
}

The UI’s side of the engine: a cheap, cloneable sender of messages.

Commands are fire-and-forget; their effect is seen in a later Event::State.

Fields

tx: Sender<Msg>

The engine thread’s message channel.

Implementations

impl Engine

pub fn command(&self, cmd: &str, args: Value)

Sends a command. Returns at once; an unknown command is logged as a warning, and a command sent after the engine has gone is dropped.

pub fn query(&self, name: &str, args: Value) -> Value

Asks a query and waits for its answer: Value::Null if the engine thread has gone or does not answer within 30 s (a large log can take that long to open ahead of it), and { "error": ... } for an unknown query.

Trait Implementations

impl Clone for Engine

fn clone(&self) -> Engine

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
