Struct MappedEvent 

pub struct MappedEvent<'a, E: Event + ?Sized> { /* private fields */ }

An Event that rewrites field names via a Sigma -> [event field] map before reading from the inner event.

Implementations

impl<'a, E: Event + ?Sized> MappedEvent<'a, E>

pub fn new(inner: &'a E, mapping: &'a HashMap<String, Vec<String>>) -> Self

Wrap inner, remapping field names via mapping. An empty mapping makes this a transparent pass-through.

Trait Implementations

impl<E: Event + ?Sized> Event for MappedEvent<'_, E>

fn get_field(&self, path: &str) -> Option<EventValue<'_>>

Look up a field by name. Supports dot-notation for nested access.

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

Check if any string value anywhere in the event satisfies a predicate. Used by keyword detection.

fn all_string_values(&self) -> Vec<Cow<'_, str>>

Collect all string values in the event.

fn to_json(&self) -> Value

Materialize the event as a serde_json::Value.

fn field_keys(&self) -> Vec<Cow<'_, str>>

Collect the names of every leaf field in the event, with nested objects flattened to dot-separated paths (e.g. actor.id). Intermediate object names are not emitted; only leaves count. Arrays contribute their parent path once; per-index suffixes are not emitted.
