Crate for doing IO on RIFF-formatted files

Examples

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

// Some ids to use while creating chunkslet 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)])]);letmut file =File::create("somefile.riff")?;contents.write(&mut file)?;
