Under the conditions specified in [[dcl.init]](dcl.init "9.5 Initializers"), as
part of an initialization of an object of non-class type,
a conversion function can be invoked to convert an initializer
expression of class type to the type of the object
being initialized[.](#1.sentence-1)

Overload resolution is used to select the
conversion function to be invoked[.](#1.sentence-2)

Assuming that “cv T” is the
type of the object being initialized,
the candidate functions are selected as follows:

- [(1.1)](#1.1)

The permissible types for non-explicit conversion functions are
those that can be converted to type T via a standard conversion sequence ([[over.ics.scs]](over.ics.scs "12.2.4.2.2 Standard conversion sequences"))[.](#1.sentence-3)
  For direct-initialization,
the permissible types for explicit conversion functions are
those that can be converted to type T with a (possibly trivial) qualification conversion ([[conv.qual]](conv.qual "7.3.6 Qualification conversions"));
otherwise there are none[.](#1.1.sentence-2)

The argument list has one argument, which is the initializer expression[.](#2.sentence-1)

[*Note [1](#note-1)*:

This argument will be compared against
the object parameter of the conversion functions[.](#2.sentence-2)
