Struct FileChunk 

pub struct FileChunk {
    pub file_id: String,
    pub file_name: String,
    pub file_size: u64,
    pub total_chunks: u32,
    pub chunk_index: u32,
    pub chunk_data: Vec<u8>,
    pub file_checksum: String,
}

A file chunk message.

Fields

file_id: String

Unique file identifier.

file_name: String

Original file name.

file_size: u64

Total file size in bytes.

total_chunks: u32

Total number of chunks.

chunk_index: u32

Index of this chunk (0-based).

chunk_data: Vec<u8>

Chunk data (base64-encoded in JSON).

file_checksum: String

Checksum of the complete file (SHA256 hex string).

Implementations

impl FileChunk

pub fn to_json(&self) -> Result<String, Error>

Serializes to JSON (kept for backward compatibility).

pub fn from_json(json: &str) -> Result<Self, Error>

Deserializes from JSON (kept for backward compatibility).

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

Serializes to a compact binary format, avoiding base64/JSON overhead.

Wire format (all multi-byte integers are little-endian):

[file_id_len:4][file_id][file_name_len:4][file_name]
[file_size:8][total_chunks:4][chunk_index:4]
[chunk_data_len:4][chunk_data]
[checksum_len:4][checksum]

pub fn from_bytes(data: &[u8]) -> Result<Self, ChunkDecodeError>

Deserializes from the compact binary format produced by to_bytes.
