Struct DataPhasePacket 

pub struct DataPhasePacket {
    pub data: Vec<u8>,
}

McuBoot data phase packet structure

Represents a data phase packet that carries additional data for commands that require it. The data phase packet is sent after the command packet when the command’s CommandFlag::HasDataPhase flag is set. This allows for transmission of variable-length data that exceeds the command packet’s parameter capacity.

Usage

If using the McuBoot high-level interface, data phase packets are automatically sent when a command requires additional data. However, if you’re working with command packets directly, you’ll need to create and send the corresponding data phase packet manually for commands that have the CommandFlag::HasDataPhase flag set.

Fields

data: Vec<u8>

Raw data payload to be transmitted

Trait Implementations

impl Packet for DataPhasePacket

fn get_code() -> u8

Returns the packet type identifier for data phase packets (0xA5)

impl PacketConstruct for DataPhasePacket

fn construct(&self) -> Vec<u8>

Constructs a complete data phase packet ready for transmission

This method wraps the data payload with the appropriate McuBoot protocol header to create a properly formatted data phase packet. The header includes the packet type, length, and CRC checksum as required by the protocol.

Returns

A Vec<u8> containing the complete data phase packet with protocol header:

• Start byte (0x5A)
• Packet code (0xA5)
• Length (2 bytes, little-endian)
• CRC16 (2 bytes, little-endian)
• Data payload (variable length)

impl PacketParse for DataPhasePacket

fn parse(bytes: &[u8]) -> Result<DataPhasePacket, CommunicationError>

Creates a DataPhasePacket from raw bytes

Arguments

• bytes - Raw data bytes to be stored in the packet

Returns

A Result containing the new DataPhasePacket with the provided data

Note

This method always succeeds as data phase packets can contain any arbitrary byte sequence as their payload.
