Expand description

Read a .blend file to extract DNA information first.

Verbosity flags:

  • print_dna
  • print_pointers

Input

  • path - a path to a folder/filename.blend

Return values (&mut):

  • dna_types_hm - A HashMap with a type name (e.g. “float”) and it’s byte size as u16
  • dna_structs_hm - A HashMap with a struct name (e.g. “Camera”) and it’s members (DnaStrC)
  • dna_pointers_hm - A HashMap with 2 usize values (real memory address stored in file, and byte position within .blend file)
  • dna_2_type_id - Use sdna_nr to find type_id
  • types - Vec of type names (e.g. “char”, “short”, “double”)
  • bytes_read - Should match the file size on disk
