== Description


This function replaces the segment at        the specified position.        Reserved characters in the string are        automatically escaped.        Escapes in the string are preserved.

All iterators that are equal to        `pos` or come after are invalidated.


=== Complexity

Linear in `s.size() + this‐>url().encoded_resouce().size()`.


=== Exception Safety

Strong guarantee.        Calls to allocate may throw.



== Exceptions


|===
| Name | Thrown on

| `system_error`
| The string contains an invalid percent‐encoding.


|===

== Return Value


An iterator to the replaced segment.



== Parameters


|===
| Name | Description

| *pos*
| An iterator to the segment.


| *s*
| The string to assign.


| *from*
| The first element in the range of segments to replace.


| *to*
| One past the last element in the range of segments to replace.


| *init*
| The list of segments to assign.


| *first*
| The first element in the new range of segments.


| *last*
| One past the last element in the new range of segments.
