pub static BYTE_SLICE_IN_PACKED_STRUCT_WITH_DERIVE: &Lint
Expand description
The byte_slice_in_packed_struct_with_derive
lint detects cases where a byte slice field
([u8]
) or string slice field (str
) is used in a packed
struct that derives one or
more built-in traits.
Example
#[repr(packed)]
#[derive(Hash)]
struct FlexZeroSlice {
width: u8,
data: [u8],
}
{{produces}}
Explanation
This was previously accepted but is being phased out, because fields in packed structs are
now required to implement Copy
for derive
to work. Byte slices and string slices are a
temporary exception because certain crates depended on them.
