Struct Event 

pub struct Event<'a> { /* private fields */ }

A reference to a JSON event for field access during evaluation.

Flat keys are checked first: "actor.id" as a single key takes precedence over {"actor": {"id": ...}} nested traversal.

Implementations

impl<'a> Event<'a>

pub fn from_value(value: &'a Value) -> Self

Wrap a JSON value as an event.

pub fn get_field(&self, path: &str) -> Option<&'a Value>

Get a field value by name, supporting dot-notation for nested access.

Checks for a flat key first (exact match), then falls back to dot-separated traversal. When a path segment yields an array, each element is tried and the first match is returned (OR semantics).

pub fn all_string_values(&self) -> Vec<&'a str>

Iterate over all string values in the event (for keyword detection).

Recursively walks the entire event object and yields every string value found, including inside nested objects and arrays. Traversal is capped at 64 levels of nesting to prevent stack overflow.

pub fn any_string_value(&self, pred: &dyn Fn(&str) -> bool) -> bool

Check if any string value in the event satisfies a predicate.

Short-circuits on the first match, avoiding the allocation of collecting all string values into a Vec.

pub fn as_value(&self) -> &'a Value

Access the underlying JSON value.

Trait Implementations

impl<'a> Debug for Event<'a>

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

Formats the value using the given formatter.
