ParserEvent

Enum ParserEvent 

Source
pub enum ParserEvent<'a> {
    StartObject,
    EndObject,
    StartArray,
    EndArray,
    Key(Cow<'a, str>),
    String(Cow<'a, str>),
    Number(JsonNumber),
    Boolean(bool),
    Null,
}
Expand description

A single event emitted by the StreamingParser.

The parser is an Iterator that yields these events, allowing you to react to JSON data as it’s being parsed without loading the entire structure into memory.

Variants§

§

StartObject

The start of a JSON object ({).

§

EndObject

The end of a JSON object (}).

§

StartArray

The start of a JSON array ([).

§

EndArray

The end of a JSON array (]).

§

Key(Cow<'a, str>)

A JSON object key (e.g., "name": ...).

§

String(Cow<'a, str>)

A JSON string value (e.g., ... : "value").

§

Number(JsonNumber)

A JSON number value (e.g., 123, -0.5, 1e10).

§

Boolean(bool)

A JSON boolean value (true or false).

§

Null

A JSON null value.
