Struct TruncationEvent 

pub struct TruncationEvent { /* private fields */ }

GSM truncation marker event.

Emitted when Arena’s Player.log writes the [Message summarized because one or more GameStateMessages exceeded the 50 GameObject or 50 Annotation limit.] marker in place of a normal GameStateMessage JSON body. The truncated GSM’s body is irrecoverable from the log; this event surfaces the signal so downstream consumers (deck tracker) can mark the next gsm_id as crossing a data-loss gap.

Following the header-only convention used by LogFileRotatedEvent and DetailedLoggingStatusEvent: timestamp lives in EventMetadata, the payload carries {"object_count": N, "annotation_count": M}. raw_bytes is empty because the marker has no parseable body and downstream fingerprinting derives no value from preserving the fixed-form marker text.

Implementations

impl TruncationEvent

pub fn new(metadata: EventMetadata, payload: Value) -> Self

Constructs a new event with the given metadata and payload.

pub fn metadata(&self) -> &EventMetadata

Returns the shared event metadata.

pub fn payload(&self) -> &Value

Returns the parsed JSON payload.

impl TruncationEvent

pub fn new_truncation( timestamp: Option<DateTime<Utc>>, object_count: u32, annotation_count: u32, ) -> Self

Creates a truncation event from parsed marker counts.

pub fn object_count(&self) -> Option<u32>

Returns the truncated GSM’s reported game-object count, or None if the payload was manually constructed without the field.

pub fn annotation_count(&self) -> Option<u32>

Returns the truncated GSM’s reported annotation count, or None if the payload was manually constructed without the field.

Trait Implementations

impl Clone for TruncationEvent

fn clone(&self) -> TruncationEvent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TruncationEvent

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TruncationEvent

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TruncationEvent

fn eq(&self, other: &TruncationEvent) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TruncationEvent

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
