Struct Signal 

pub struct Signal {
    pub id: String,
    pub symbol: String,
    pub kind: SignalType,
    pub confidence: f64,
    pub timestamp: DateTime<Utc>,
    pub source: String,
    pub metadata: Value,
}

A richer signal carrying confidence, source, and arbitrary metadata for logging.

The framework’s execution layer doesn’t interpret metadata — it’s there so a brain can record its rationale for post-hoc analysis.

Fields

id: String

Unique identifier for this signal (typically {brain_name}-{counter}).

symbol: String

Symbol the signal is for, as a free-form string.

kind: SignalType

Buy / Sell / Hold / Close.

confidence: f64

Confidence in [0.0, 1.0]. A brain producing a Buy with confidence 0.2 is saying “I’m barely sure about this” — the risk layer can choose to size down or reject.

timestamp: DateTime<Utc>

Time the brain emitted this signal.

source: String

Brain name that emitted the signal — useful for routing in multi-brain bots.

metadata: Value

Free-form. Use serde_json::json!({...}) to populate.

Trait Implementations

impl Clone for Signal

fn clone(&self) -> Signal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signal

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signal

fn deserialize<__D>( __deserializer: __D, ) -> Result<Signal, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Signal

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
