[section:overwrite overwrite]

[heading Prototype]

``
template<
    class SinglePassRange1,
    class SinglePassRange2
    >
void overwrite(const SinglePassRange1& from,
               SinglePassRange2& to);
``

[heading Description]

`overwrite` assigns the values from the range `from` into the range `to`.

[heading Definition]

Defined in the header file `boost/range/algorithm_ext/overwrite.hpp`

[heading Requirements]

# `SinglePassRange1` is a model of the __single_pass_range__ Concept.
# `SinglePassRange2` is a model of the __single_pass_range__ Concept.
# `SinglePassRange2` is mutable.
# `distance(SinglePassRange1) <= distance(SinglePassRange2)`
# `SinglePassRange1`'s value type is convertible to `SinglePassRange2`'s value type.

[heading Complexity]

Linear. `distance(rng1)` assignments are performed.
