pub fn combine(shares: &[(u8, &[u8])], out: &mut [u8]) -> Result<()>Expand description
Recover a secret from shares given as (index, bytes).
Pass at least threshold shares; more are fine. With fewer, the result is
a wrong secret rather than an error – see the module note. Every share
must be out.len() bytes, and indices must be nonzero and distinct; at
least two shares are required.
