Expand description
Custom derive for zerofrom::ZeroFrom
,
This implements ZeroFrom<Ty> for Ty
for types
without a lifetime parameter, and ZeroFrom<Ty<'data>> for Ty<'static>
for types with a lifetime parameter.
Apply the #[zerofrom(clone)]
attribute to a field if it doesn’t implement
Copy or ZeroFrom; this data will be cloned when the struct is zero_from’ed.
Apply the #[zerofrom(maybe_borrow(T, U, V))]
attribute to the struct to indicate
that certain type parameters may themselves contain borrows (by default
the derives assume that type parameters perform no borrows and can be copied or cloned).
In rust versions where this issue is fixed,
#[zerofrom(may_borrow)]
can be applied directly to type parameters.
