Enum TriggerCondition 

pub enum TriggerCondition {
    Label {
        key: String,
        value: String,
    },
    Expression(Arc<dyn Fn(&TriggerContext) -> bool + Send + Sync>),
}

A condition that must be satisfied for an EventTriggerRule to fire.

All conditions on a rule are evaluated with AND semantics: the rule fires only when every condition returns true. For OR semantics, create separate rules.

Examples

use ironflow_runtime::trigger::event::TriggerCondition;

let cond = TriggerCondition::Label {
    key: "env".to_string(),
    value: "prod".to_string(),
};
assert!(matches!(cond, TriggerCondition::Label { .. }));

Variants

Label

The source run must carry a label with this exact key-value pair.

Fields

key: String

Label key to check.

value: String

Expected label value.

Expression(Arc<dyn Fn(&TriggerContext) -> bool + Send + Sync>)

An arbitrary predicate evaluated against the TriggerContext.

Uses Arc so the condition is Clone + Send + Sync.

Implementations

impl TriggerCondition

pub fn evaluate(&self, ctx: &TriggerContext) -> bool

Evaluate this condition against the given context.

Examples

use std::collections::HashMap;
use ironflow_runtime::trigger::event::{TriggerCondition, TriggerContext};
use rust_decimal::Decimal;

let ctx = TriggerContext {
    labels: HashMap::from([("env".to_string(), "prod".to_string())]),
    error: None,
    cost_usd: Decimal::ZERO,
    duration_ms: 0,
};
let cond = TriggerCondition::Label {
    key: "env".to_string(),
    value: "prod".to_string(),
};
assert!(cond.evaluate(&ctx));

Panics

Does not panic. If an Expression closure panics, the panic is caught and the condition evaluates to false.

Trait Implementations

impl Clone for TriggerCondition

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriggerCondition

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