is_nothrow_constructible Class
The latest version of this topic can be found at is_nothrow_constructible Class.
Tests whether a type is constructible and is known not to throw when the specified argument types are used.
Syntax
template <class T, class... Args>
struct is_nothrow_constructible;
Parameters
T
The type to query.
Args
The argument types to match in a constructor of T.
Remarks
An instance of the type predicate holds true if the type T is constructible by using the argument types in Args, and the constructor is known by the compiler not to throw; otherwise it holds false. Type T is constructible if the variable definition T t(std::declval<Args>()...); is well-formed. Both T and all the types in Args must be complete types, void, or arrays of unknown bound.
