Non blocking deserialize

[dbagnara]

Is there a way to prevent deserialize from blocking?

For example, is it possible to either push a stream into the JsonDocument using a ficticious method addSerialData()
StaticJsonDocument<256> doc ; doc.addSerialData( "[1," ); doc.addSerialData( '2' ); doc.addSerialData( ",3]" );

Or resume a partial deserialization.

StaticJsonDocument<256> doc ; deserializeJson( doc, "[1,2," ); deserializeJson( doc, "3]" );

Thanks

Hi @dbagnara,

No, ArduinoJson doesn't support incremental/partial deserialization.
I wish to add this feature at some point, but I'm afraid it will increase the code size dramatically.

As a workaround, I suggest that you use a StringStream as a temporary buffer and call deserializeJson() when the message is complete.

Best regards,
Benoit
