Event

Enum Event 

Source
pub enum Event {
    StartObject,
    EndObject,
    StartArray,
    EndArray,
    Key(JsonStr),
    String(JsonStr),
    Number(JsonNum),
    Bool(bool),
    Null,
}
Expand description

A single event from the streaming parser.

The parser emits these in document order. Containers are delimited by matched Start*/End* pairs. Inside an object, every value event is preceded by a Key event for that field.

Event is 16 bytes — (JsonStr|JsonNum: 8 bytes) + (tag: 1 byte) + 7 bytes padding. This fits in one xmm register, so next_event returns it without spilling to the stack — measurable in profiles as ~12% of typed-parse runtime saved compared to the previous 32-byte representation.
