Enum PacketData

pub enum PacketData {
    Parsed(Box<Packet>),
    Buffer {
        packet_type: PacketType,
        data: Vec<u8>,
    },
    Offset {
        packet_type: PacketType,
        offset: u32,
    },
}

TRN packet data, that may or may not be loaded in memory or parsed

Variants

Parsed(Box<Packet>)

Packet data has been fully loaded and parsed

Buffer

Packet data has been loaded in memory, but not parsed

Fields

packet_type: PacketType

Packet type

data: Vec<u8>

Packet data block, without the type + length header

Offset

Unloaded packet. The packet has not been parsed nor loaded in memory.

Fields

packet_type: PacketType

Expected packet type. Packet data block may indicate a different type.

offset: u32

offset to the packet data block

Implementations

impl PacketData

pub fn get_type(&self) -> PacketType

Returns the packet type, regardless of whether it has been parsed or not

pub fn from_bytes_parse( input: &[u8], expected_packet_type: Option<PacketType>, ) -> NWNParseResult<'_, Self>

Parse a packet data block, including its type and size header. Returns a PacketData::Parsed

pub fn from_bytes_clone( input: &[u8], expected_packet_type: Option<PacketType>, ) -> NWNParseResult<'_, Self>

Store packet data without parsing its content. Returns a PacketData::Buffer

pub fn to_bytes(&self) -> Vec<u8>

Returns the serialized data block for the packet, with the type and size header

pub fn load_offset( &mut self, buffer: &[u8], buffer_offset: u32, ) -> NWNParseResult<'_, &[u8]>

Converts self from a PacketData::Offset into a PacketData::Buffer

pub fn parse_offset( &mut self, buffer: &[u8], buffer_offset: u32, ) -> NWNParseResult<'_, ()>

Converts self from a PacketData::Offset into a PacketData::Parsed

pub fn parse_buffer(&mut self) -> NWNParseResult<'_, ()>

Converts self from a PacketData::Buffer into a PacketData::Parsed

pub fn as_parsed(&self) -> Option<&Packet>

Trait Implementations

impl Debug for PacketData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
