Public Member Functions
constexpr auto	as_ptr () const noexcept
	Returns a const pointer to the guarded value.
constexpr auto	as_mut_ptr () noexcept
	Returns a mutable pointer to the guarded value.

Static Public Member Functions
static auto	make (T &&inner, F &&f) -> Self
	Creates a DropGuard wrapping the value and drop function.

Detailed Description

template<typename T, typename F>
struct rstd::mem::drop_guard::DropGuard< T, F >

A scope guard that invokes a callable on the inner value when dropped.

On destruction, the inner value is moved out and passed to the stored callable F. Useful for ensuring cleanup logic runs even when leaving scope via an exception.

Template Parameters

T	The guarded value type.
F	A callable type invoked as f(T*) on drop.
