Function dumpmask

Source 
pub(crate) fn dumpmask(mask: u64) -> String
Expand description

Given a bitmask, return a list of the bits set in the mask, as a String in the format expected by Tor consensus documents.

This implementation constructs ranges greedily. For example, the bitmask 0b0111011 will be represented as 0-1,3-5, and not 0,1,3,4,5 or 0,1,3-5.
