riff

Crate for doing IO on RIFF-formatted files

Examples

let mut file = File::open("somefile.wav")?;
let chunk = riff::Chunk::read(&mut file, 0)?;
for child in chunk.iter(&mut file) {
 println!(child.id());
}

// Some ids to use while creating chunks
let smpl_id: ChunkId = ChunkId { value: [0x73, 0x6D, 0x70, 0x6C] };
let test_id: ChunkId = ChunkId { value: [0x74, 0x65, 0x73, 0x74] };
let tst1_id: ChunkId = ChunkId { value: [0x74, 0x73, 0x74, 0x31] };
let tst2_id: ChunkId = ChunkId { value: [0x74, 0x73, 0x74, 0x32] };
let str1 = "hey this is a test".as_bytes().to_vec();
let str2 = "hey this is another test".as_bytes().to_vec();
let str3 = "final test".as_bytes().to_vec();
let contents = ChunkContents::Children(
 riff::RIFF_ID,
 smpl_id,
 vec![
 ChunkContents::Children(
 riff::LIST_ID,
 tst1_id,
 vec![
 ChunkContents::Data(test_id, str1),
 ChunkContents::Data(test_id, str2)
 ]),
 ChunkContents::Children(
 riff::LIST_ID,
 tst2_id,
 vec![
 ChunkContents::Data(test_id, str3)
 ]
 )
 ]);
let mut file = File::create("somefile.riff")?;
contents.write(&mut file)?;
