Parsers for packets sent from App Aria and data structures to store their contents.

src/mwings/parsers/app_aria.py

`PacketParser`

Static class parser that interprets packets representing data sent from the Aria app

Inherits: common.PacketParserBase

Members inherited from the base class are listed.

`is_valid()`

is_valid(bare_packet)

Checks whether the given raw packet is valid.

Arguments

Returns

Type	Value	Description
`bool`	`True`	Valid, parsable
	`False`	Invalid, not parsable

`parse()`

parse(bare_packet)

You can also pass a dictionary unpacked with **.

In addition to the variables specified in the constructor arguments, the following @computed_field are available.

`mwings_implementation`	`str`	MWings implementation (only `"python"`)
`mwings_version`	`str`	MWings version (in PEP440 format)
`hostname`	`str`	Host machine name

Applicable field_validator

source_logical_id: Automatically validates the value range
- check_source_logical_id(lid)
time_parsed: Automatically validates that a timezone is attached
- datetime_must_be_clear(dt)

Applicable field_serializer

packet_type: Serializes the enum name as-is for JSON etc.
- serialize_packet_type(packet_type)
source_serial_id: Serializes as a hexadecimal string for JSON etc.
- serialize_source_serial_id(source_serial_id)
time_parsed: Serializes as ISO 8601 string for JSON etc.
- serialize_time_parsed(dt)
magnet_state: Serializes the enum name as-is for JSON etc.
- serialize_magnet_state(magnet_state)

`to_df()`

to_df(include=None, exclude=None, verbose=True)

Converts the parsed data to a pandas DataFrame format.
