Struct PacketHeader 

pub struct PacketHeader {
    pub length: u64,
    pub packet_hash: [u8; 16],
    pub recovery_set_id: RecoverySetId,
    pub packet_type: PacketType,
}

Parsed 64-byte packet header.

Fields

length: u64

Total packet length (header + body), always >= 64 and multiple of 4.

packet_hash: [u8; 16]

MD5 of bytes 32..length (recovery_set_id + type + body).

recovery_set_id: RecoverySetId

Recovery set this packet belongs to.

packet_type: PacketType

The packet type.

Implementations

impl PacketHeader

pub fn parse(data: &[u8], offset: u64) -> Result<Self>

Parse a 64-byte header from raw bytes.

offset is used only for error reporting (position in file/stream). This does NOT validate the packet hash (needs the full packet body).

pub fn validate_hash(&self, full_packet: &[u8], offset: u64) -> Result<()>

Validate the packet hash against the full packet data (bytes 0..length).

The hash covers bytes 32..length (recovery_set_id + type + body).

pub fn body_length(&self) -> u64

Size of the packet body (everything after the 64-byte header).
