Struct SequenceContext 

pub struct SequenceContext {
    pub captured: FxHashMap<String, Event>,
    pub previous: Option<Event>,
}

Context for evaluating sequence filters

Fields

captured: FxHashMap<String, Event>

Captured events by alias

previous: Option<Event>

Previous event in sequence (accessible as $)

Implementations

impl SequenceContext

pub fn new() -> Self

pub fn empty() -> &'static Self

Returns a reference to a shared empty context for read-only operations. PERF: Avoids allocating a new HashMap for each operation that doesn’t need captured events.

pub fn with_captured(self, alias: String, event: Event) -> Self

pub fn get(&self, alias: &str) -> Option<&Event>
