v0.5.0

• Added missing VkFormat variants to Format (#39).

• Added shorthand Reader accessors: color_primaries(), transfer_function(), color_model(), is_alpha_premultiplied(), writer(), and basic_dfd() (#43).

• Added DFD generation: dfd::Basic::from_format() and dfd::Basic::from_format_with() for constructing basic DFD blocks from a Format.

• Moved all Data Format Descriptor (DFD) types into new submodule called dfd and renamed them to be more understandable.

  • DfdBlock -> dfd::Block
  • DfdHeader -> dfd::BlockHeader
  • DfdBlockBasic -> dfd::Basic
  • DfdBlockHeaderBasic -> dfd::BasicHeader

  The following types moved into the dfd module unchanged.

  • ChannelTypeQualifiers
  • ColorModel
  • ColorPrimaries
  • DataFormatFlags
  • SampleInformation
  • TransferFunction

• Added dfd::Block serialization: serialized_length(), to_bytes(), to_vec(), parse()

• dfd::Block is now an owned enum (Basic(Basic) | Unknown { header, data }) instead of a borrowed struct

• dfd::BasicHeader merged into dfd::Basic, which now owns its sample_information: Vec<SampleInformation> instead of providing a lazy iterator. dfd::BasicHeader::LENGTH is now dfd::Basic::FIXED_LENGTH

• Reader::dfd_blocks() returns &[dfd::Block] instead of impl Iterator<Item = dfd::Block<'_>>
