Available on crate feature dial9 only.

Trait implemented by #[derive(TraceEvent)] for compile-time event types.

Required Associated Types

type Ref<'a>

Decoded form of this event, potentially borrowing from the input buffer.

Required Methods

fn event_name() -> &'static str

The event type name (used in schema registration).

fn field_defs() -> Vec<FieldDef>

Field definitions for schema registration. When has_timestamp() is true, the timestamp is NOT included here — it is encoded in the event frame header.

fn timestamp(&self) -> u64

Return the event’s timestamp in nanoseconds.

fn encode_fields<W>(&self, enc: &mut EventEncoder<'_, W>) -> Result<(), Error>

where W: Write,

Encode this event’s non-timestamp fields into the encoder.

fn decode<'a>( timestamp_ns: Option<u64>, fields: &[FieldValueRef<'a>], field_defs: &[FieldDef], ) -> Option<Self::Ref<'a>>

Decode from field values using field definitions for name resolution. timestamp_ns is the absolute timestamp from the event header (if present).

Provided Methods

fn has_timestamp() -> bool

Whether this event type carries a packed timestamp in the event header.

fn schema_entry() -> SchemaEntry

Build a SchemaEntry for this event type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
