Constant libjxl_sys::JXL_DEC_NEED_MORE_INPUT

pub const JXL_DEC_NEED_MORE_INPUT: JxlDecoderStatus = 2;

The decoder needs more input bytes to continue. Before the next @ref JxlDecoderProcessInput call, more input data must be set, by calling @ref JxlDecoderReleaseInput (if input was set previously) and then calling @ref JxlDecoderSetInput. @ref JxlDecoderReleaseInput returns how many bytes are not yet processed, before a next call to @ref JxlDecoderProcessInput all unprocessed bytes must be provided again (the address need not match, but the contents must), and more bytes must be concatenated after the unprocessed bytes.
