is_trivially_assignable Class

Tests whether a value of From type can be trivially assigned to To type

Syntax

template <class To, class From>  
struct is_trivially_assignable;

Parameters

To
The type of the object that receives the assignment.

From
The type of the object that provides the value.

Remarks

The expression declval<To>() = declval<From>() must be well-formed, and must be known to the compiler to require no non-trivial operations. Both From and To must be complete types, void, or arrays of unknown bound.

Requirements

Header: <type_traits>

Namespace: std
