Struct AlertRule 

#[non_exhaustive]
pub struct AlertRule {
    pub symbol: String,
    pub condition: AlertCondition,
    pub repeat: bool,
}

A symbol paired with the condition that should trigger an alert.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

symbol: String

Symbol this rule watches (matched against PriceUpdate::id).

condition: AlertCondition

Predicate to evaluate.

repeat: bool

Fire repeatedly (re-arming whenever the condition stops holding) instead of once.

Implementations

impl AlertRule

pub fn new(symbol: impl Into<String>, condition: AlertCondition) -> Self

A one-shot rule: fires the first time the condition holds.

pub fn repeating(self) -> Self

Fire every time the condition becomes true again.
