Struct TriggerFilter 

pub struct TriggerFilter {
    pub event_type: Option<String>,
    pub source: Option<String>,
    pub subject_pattern: Option<String>,
    pub attributes: Vec<(String, String)>,
}

Filter criteria for a Trigger

All non-None fields must match (AND logic). A filter with all fields set to None matches every event.

Fields

event_type: Option<String>

Match events with this exact event_type

source: Option<String>

Match events from this source

subject_pattern: Option<String>

Match events whose subject matches this pattern (supports > and * wildcards)

attributes: Vec<(String, String)>

Match events that contain all of these metadata key-value pairs
