Source 
#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_chirpstack_uplink_parse(
    text: *const u8,
    text_len: usize,
    out_uplink: *mut *mut PamojaChirpstackUplink,
) -> PamojaStatus
Expand description

Reads an uplink event from the JSON ChirpStack published.

§Arguments

  • text - the MQTT message’s payload, UTF-8 JSON.
  • text_len - its length.
  • out_uplink - receives the event.

§Returns

PamojaStatus::Ok on success, with *out_uplink set to a handle the caller must release with pamoja_chirpstack_uplink_free.

§Errors

Returns PamojaStatus::InvalidArgument if a pointer is null, and PamojaStatus::Codec for text that is not a JSON object, an event with no device EUI, or a field that does not read as what it should, with the field named by pamoja_last_error.

§Safety

text must point to text_len readable bytes when that is non-zero, and out_uplink must be writable.
