Hi there,

I'm designing a library which has a Buffer module that allows to contain binary data. Think of it as a string just with less features :-P ... except it is mutable. Now I'm writing a companion module called Buffer.Segment that allows access to just a limited part of the buffer which is defined by an offset and a length. I'd plan the API look like this:

b  = Buffer( 1024 )      -- buffer with 124 bytes
s = Segment( b ) -- creates a segment starting at the first byte of the buffer as long as the buffer itself
s1 = Segment( 128, 256 ) -- Segment with 128 byte offset and 256 bytes length
s2 = Segment( 439 )      -- this is the question, shall this be:

- a segment starting at byte 439 and have a length to the end of the buffer, or
                     - a segment starting at first byte being 439 bytes long

I don't think there is a 'right' answer, but to all those people who work with this kind of stuff, what would feel more natural to you? Also, does Segment( offset, length ) makes more sense than Segment( length, offset ) ?

Thanks for the input,

 - Tobias
