Struct TypeOpsDirect 

#[repr(C)]
pub struct TypeOpsDirect {
    pub drop_in_place: unsafe fn(*mut ()),
    pub default_in_place: Option<unsafe fn(*mut ())>,
    pub clone_into: Option<unsafe fn(src: *const (), dst: *mut ())>,
    pub is_truthy: Option<TruthyFn>,
}

Type-specific operations for concrete types (uses thin pointers).

Used for scalars, String, user-defined structs/enums, etc.

These operations must be monomorphized per-type because they need to know the concrete type T at compile time:

• drop_in_place: Needs to call T’s destructor
• default_in_place: Needs to construct T::default()
• clone_into: Needs to call T::clone()

Fields

drop_in_place: unsafe fn(*mut ())

Drop the value in place.

Safety

The pointer must point to a valid, initialized value of the correct type.

default_in_place: Option<unsafe fn(*mut ())>

Construct a default value in place.

Returns None if the type doesn’t implement Default.

Safety

The pointer must point to uninitialized memory of sufficient size and alignment.

clone_into: Option<unsafe fn(src: *const (), dst: *mut ())>

Clone a value into uninitialized memory.

Returns None if the type doesn’t implement Clone.

Safety

• src must point to a valid, initialized value
• dst must point to uninitialized memory of sufficient size and alignment

is_truthy: Option<TruthyFn>

Truthiness predicate for this type. When absent, the type is never considered truthy.
