Function Details

encode_range/2

  encode_range(Range::range() | invalid_range, Size::non_neg_integer()) -> ByteRange::iolist()
  

Encode Range to a Content-Range value.

file_size/1

  file_size(Filename) -> Size | {error, Reason}
  

• Filename = file:name_all()
• Size = non_neg_integer()
• Reason = file:posix() | badarg | invalid_file

Get the size in bytes of the file.

normalize_range/2

  normalize_range(RangeOrSet, Size) -> Normalized
  

• RangeOrSet = any()
• Size = integer()
• Normalized = range() | undefined | invalid_range

If a valid byte-range, or byte-range-set of size 1 is supplied, returns a normalized range in the format {Offset, Length}. Returns undefined when an empty byte-range-set is supplied and the atom invalid_range in all other cases.
