unsafe fn merge<T, F>(v: &mut [T], mid: usize, buf: *mut T, is_less: &mut F)where
F: FnMut(&T, &T) -> bool,
🔬This is a nightly-only experimental API. (
slice_internals
)Expand description
Merges non-decreasing runs v[..mid]
and v[mid..]
using buf
as temporary storage, and
stores the result into v[..]
.
Safety
The two slices must be non-empty and mid
must be in bounds. Buffer buf
must be long enough
to hold a copy of the shorter slice. Also, T
must not be a zero-sized type.
