I have written these functions for my own use, but I would like it better if they were inside std::bitv:
/**
* Transform a byte-vector into a bitv. Each byte becomes 8 bits,
* with the most significant bits of each byte coming first. Each
* bit becomes true if equal to 1 or false if equal to 0.
*/
fn from_bytes(bytes: [u8]) -> bitv;
/**
* Transform a [bool] into a bitv by converting each bool into a bit.
*/
fn from_bools(bools: [bool]) -> bitv;
/**
* Create a bitv of the specified length where the value at each
* index is f(index).
*/
fn from_fn(len: uint, f: fn(index: uint) -> bool) -> bitv;
(there are also corresponding to_bytes/to_bools methods).
As a separate but related issue, I think it would be nice if the bitv type was turned into a class and its internal data marked as private members.
As either of these requests pleasing to you? I can provide pull requests (with tests/docs/etc) if they are.
