public IBig buffer, repr. #7

Closed ertosns closed 1 year ago

ertosns commented 1 year ago

i need to do big arith using dashu at some project, and read the integer 'iBig' buffer raw bytes, which is private, i can't read integer/repr from IBig, on the other hand as_sign_words, only return a single word.

cmpute commented 1 year ago

The signature of as_sign_words is

pub fn as_sign_words(&self) -> (Sign, &[Word])

It will return a reference to the underlying word array. Currently I'm not planning to allow taking the ownership of the word buffer, which requires exposing the internal representation as stable public API.

@cmpute ok i see, i tried on a small number it returned single word, i thought it return the Small TypedRepr, i checked the code again, it return all held bytes in union ReprData. thanks.
