Trait ActorIndicator 

pub trait ActorIndicator: Any {
    // Required methods
    fn key(&self) -> usize;
    fn as_any(&self) -> &dyn Any;
    fn initialized(&self) -> Result<bool>;
    fn handle_quote(&self, quote: &QuoteTick) -> Result<()>;
    fn handle_trade(&self, trade: &TradeTick) -> Result<()>;
    fn handle_bar(&self, bar: &Bar) -> Result<()>;
}

Indicator callback interface used by the actor core.

Required Methods

fn key(&self) -> usize

Returns a stable key used to de-duplicate indicator registrations.

fn as_any(&self) -> &dyn Any

Returns this indicator as Any for adapter-specific downcasting.

fn initialized(&self) -> Result<bool>

Checks if the indicator is initialized.

Errors

Returns an error if the indicator cannot report readiness.

fn handle_quote(&self, quote: &QuoteTick) -> Result<()>

Handles a quote tick.

Errors

Returns an error if the indicator cannot handle the quote tick.

fn handle_trade(&self, trade: &TradeTick) -> Result<()>

Handles a trade tick.

Errors

Returns an error if the indicator cannot handle the trade tick.

fn handle_bar(&self, bar: &Bar) -> Result<()>

Handles a bar.

Errors

Returns an error if the indicator cannot handle the bar.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
