Struct PacketHandler

pub struct PacketHandler { /* private fields */ }

Tool that handles the serialization, encryption and authentication of packets

Implementations

impl PacketHandler

pub fn new( options: HandlerOptions, bucket_keys: Option<HashMap<BucketId, [u8; 32]>>, session_key: Option<[u8; 32]>, ) -> Self

Creates a new PacketHandler

Arguments

• options - Options for the handler. See HandlerOptions for more information
• bucket_keys - Keys for the buckets. If None, the handler will use an empty map
• session_key - The session key. If None, the handler will not be able to encrypt or authenticate packets

pub fn parse_request( &mut self, data: &[u8], ) -> Result<RequestPacket, SerializationError>

Parse a serialized and maybe encrypted request packet

Arguments

• data - The serialized packet

Returns

• Ok(RequestPacket) - The parsed packet
• Err(SerializationError) - The error that occured

pub fn parse_response( &mut self, data: &[u8], ) -> Result<ResponsePacket, SerializationError>

Parse a serialized and maybe encrypted response packet

Arguments

• data - The serialized packet

Returns

• Ok(ResponsePacket) - The parsed response packet
• Err(SerializationError) - The error that occured

pub fn serialize_request( &mut self, packet: RequestPacket, with_len: bool, ) -> Result<Vec<u8>, SerializationError>

Serialize a request packet

Arguments

• packet - The packet to serialize
• with_len - Indicates if the length of the packet should be included

Returns

• Ok(Vec<u8>) - The serialized packet
• Err(SerializationError) - The error that occured

pub fn serialize_response( &mut self, packet: ResponsePacket, with_len: bool, ) -> Result<Vec<u8>, SerializationError>

Serialize a response packet

Arguments

• packet - The packet to serialize
• with_len - Indicates if the length of the packet should be included

Returns

• Ok(Vec<u8>) - The serialized packet
• Err(SerializationError) - The error that occured
