Struct streamson_lib::streamer::Streamer

pub struct Streamer { /* fields omitted */ }

Reads parts of UTF-8 json input and emits paths e.g. reading of

{
    "People": [
        {"Height": 180, "Age": 33},
        {"Height": 175, "Age": 24}
    ]
}

should emit (index and path)

Start( 0, ParsedKind::Obj) // Streamer.path == ""
Start( 1, ParsedKind::Arr) // Streamer.path == "{\"People\"}"
Start( 3, ParsedKind::Obj) // Streamer.path == "{\"People\"}[0]"
Start( 4, ParsedKind::Num) // Streamer.path == "{\"People\"}[0]{\"Height\"}"
End(   5, ParsedKind::Num)
Start( 6, ParsedKind::Num) // Streamer.path == "{\"People\"}[0]{\"Age\"}"
End(   7, ParsedKind::Num)
End(   8, ParsedKind::Obj)
Start( 9, ParsedKind::Obj) // Streamer.path == "{\"People\"}[1]"
Start(10, ParsedKind::Num) // Streamer.path == "{\"People\"}[1]{\"Height\"}"
End(  11, ParsedKind::Num)
Start(12, ParsedKind::Num) // Streamer.path == "{\"People\"}[1]{\"Age\"}"
End(  13, ParsedKind::Num)
End(  14, ParsedKind::Obj)
End(  15, ParsedKind::Arr)
End(  16, ParsedKind::Obj)
