Static rustc_lint::array_into_iter::ARRAY_INTO_ITER
source · pub static ARRAY_INTO_ITER: &Lint
Expand description
The array_into_iter
lint detects calling into_iter
on arrays.
Example
ⓘ
[1, 2, 3].into_iter().for_each(|n| { *n; });
{{produces}}
Explanation
Since Rust 1.53, arrays implement IntoIterator
. However, to avoid
breakage, array.into_iter()
in Rust 2015 and 2018 code will still
behave as (&array).into_iter()
, returning an iterator over
references, just like in Rust 1.52 and earlier.
This only applies to the method call syntax array.into_iter()
, not to
any other syntax such as for _ in array
or IntoIterator::into_iter(array)
.
