value::value (35 of 35 overloads)

value::value (35 of 35 overloads)

Construct from an initializer-list.

Synopsis

value(
    std::initializer_list< value_ref > init,
    storage_ptr sp = {});

Description

If the initializer list consists of key/value pairs, an object is created. Otherwise an array is created. The contents of the initializer list are copied to the newly constructed value using the specified memory resource.

Complexity

Linear in init.size().

Exception Safety

Strong guarantee. Calls to memory_resource::allocate may throw.

Parameters

Name	Description
`init`	The initializer list to construct from.
`sp`	A pointer to the `memory_resource` to use. The container will acquire shared ownership of the memory resource.
