pub static BOXED_SLICE_INTO_ITER: &Lint
Expand description
The boxed_slice_into_iter
lint detects calling into_iter
on boxed slices.
§Example
ⓘ
vec![1, 2, 3].into_boxed_slice().into_iter().for_each(|n| { *n; });
{{produces}}
§Explanation
Since Rust 1.80.0, boxed slices implement IntoIterator
. However, to avoid
breakage, boxed_slice.into_iter()
in Rust 2015, 2018, and 2021 code will still
behave as (&boxed_slice).into_iter()
, returning an iterator over
references, just like in Rust 1.79.0 and earlier.
This only applies to the method call syntax boxed_slice.into_iter()
, not to
any other syntax such as for _ in boxed_slice
or IntoIterator::into_iter(boxed_slice)
.
