Struct RawChunk 

pub struct RawChunk<D = Vec<u8>> { /* private fields */ }

A raw chunk in a PNA archive.

This structure represents a chunk in its most basic form, containing:

• length: The length of the chunk data in bytes
• ty: The type of the chunk (e.g., FDAT, SDAT, etc.)
• data: The actual chunk data
• crc: A CRC32 checksum of the chunk type and data

Examples

use libpna::{ChunkType, RawChunk, prelude::*};

// Create a new chunk with some data
let data = [0xAA, 0xBB, 0xCC, 0xDD];
let chunk = RawChunk::from_data(ChunkType::FDAT, data);

// Access chunk properties
assert_eq!(chunk.length(), 4);
assert_eq!(chunk.ty(), ChunkType::FDAT);
assert_eq!(chunk.data(), &[0xAA, 0xBB, 0xCC, 0xDD]);
assert_eq!(chunk.crc(), 1207118608);

Implementations

impl RawChunk

pub fn from_data<T>(ty: ChunkType, data: T) -> RawChunk

where T: Into<Vec<u8>>,

Creates a new RawChunk from the given ChunkType and bytes.

Examples

use libpna::{ChunkType, RawChunk, prelude::*};

let data = [0xAA, 0xBB, 0xCC, 0xDD];
let chunk = RawChunk::from_data(ChunkType::FDAT, data);

assert_eq!(chunk.length(), 4);
assert_eq!(chunk.ty(), ChunkType::FDAT);
assert_eq!(chunk.data(), &[0xAA, 0xBB, 0xCC, 0xDD]);
assert_eq!(chunk.crc(), 1207118608);
