Function proptest::sample::subsequence
source · [−]pub fn subsequence<T: Clone + 'static>(
values: impl Into<Cow<'static, [T]>>,
size: impl Into<SizeRange>
) -> Subsequence<T>Expand description
Sample subsequences whose size are within size from the given collection
values.
A subsequence is a subset of the elements in a collection in the order they occur in that collection. The elements are not chosen to be contiguous.
This is roughly analogous to rand::sample, except that it guarantees that
the order is preserved.
values may be a static slice or a Vec.
Panics
Panics if the maximum size implied by size is larger than the size of
values.
Panics if size is a zero-length range.
