[−][src]Function solana_libra_proptest_helpers::pick_idxs
pub fn pick_idxs<T: ?Sized, P>(
max: usize,
indexes: &T,
indexes_len: usize
) -> Vec<usize> where
T: OpsIndex<usize, Output = P>,
P: AsRef<PropIndex>,
Given a maximum value max
and a list of Index
instances, picks
integers in the range [0, max)
uniformly randomly and without duplication.
If indexes_len
is greater than max
, all indexes will be returned.
This function implements Robert Floyd's F2 algorithm for sampling without replacement.
