Struct streamson_lib::path::Emitter

pub struct Emitter { /* 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, "")
Start( 1, "{\"People\"}")
Start( 3, "{\"People\"}[0]")
Start( 4, "{\"People\"}[0]{\"Height\"}")
End(   5, "{\"People\"}[0]{\"Height\"}")
Start( 6, "{\"People\"}[0]{\"Age\"}")
End(   7, "{\"People\"}[0]{\"Age\"}")
End(   8, "{\"People\"}[0]")
Start( 9, "{\"People\"}[1]")
Start(10, "{\"People\"}[1]{\"Height\"}")
End(  11, "{\"People\"}[1]{\"Height\"}")
Start(12, "{\"People\"}[1]{\"Age\"}")
End(  13, "{\"People\"}[1]{\"Age\"}")
End(  14, "{\"People\"}[1]")
End(  15, "{\"People\"}")
End(  16, "")
