to_shared_ptr
Synopsis
Declared in <folly/Memory.h>
template<
typename T,
typename D>
std::shared_ptr<T>
to_shared_ptr(std::unique_ptr<T, D>&& ptr);Description
Convert unique_ptr to shared_ptr without specifying the template type parameter and letting the compiler deduce it.
So you can write this:
auto sptr = to_shared_ptr(getSomethingUnique<T>());
Instead of this:
auto sptr = shared_ptr<T>(getSomethingUnique<T>());
Useful when T is long, such as:
using T = foobar::FooBarAsyncClient;
Return Value
a shared_ptr that takes ownership of ptr
