##### basic_static_string::replace (8 of 14 overloads)

Replace a part of the string.

###### Synopsis

    template<
        std::size_t M>
    constexpr basic_static_string&
    replace(
        basic_static_string::const_iterator i1,
        basic_static_string::const_iterator i2,
        const basic_static_string< M, CharT, Traits >& str);

###### Description

Replaces the characters in the range `{i1, i2)` with those of `str`.

###### Precondition

`{i1, i2)` is a valid range.

###### Exception Safety

Strong guarantee.

###### Remarks

The replacement is done unchecked when the capacity of `str` differs from that of the string the function is called on.

All references, pointers, or iterators referring to contained elements are invalidated. Any past-the-end iterators are also invalidated.

###### Template Parameters

Type | Description
--- | ---
`M` | The size of the input string.

###### Return Value

`*this`

###### Parameters

Name | Description
--- | ---
`i1` | An iterator referring to the first character to replace.
`i2` | An iterator referring past the end of the last character to replace.
`str` | The string to replace with.

###### Exceptions

Type | Thrown On
--- | ---
`std::length_error` | `size() + (str.size() - std::distance(i1, i2)) > max_size()`
