[[Syntax] [Code]]
[[Pipe] [`rng | boost::adaptors::replaced(new_value, old_value)`]]
[[Function] [`boost::adaptors::replace(rng, new_value, old_value)`]]
]
* [*Precondition:]
* `new_value` is convertible to the `value_type` of the range.
* `old_value` is convertible to the `value_type` of the range.
* [*Postcondition:] For all elements `x` in the returned range, the value `x` is equal to the value of `(y == old_value) ? new_value : y` where `y` is the corresponding element in the original range.
* [*Range Category:] __forward_range__
* [*Range Return Type:] `boost::replaced_range<typeof(rng)>`
* [*Returned Range Category:] The range category of `rng`.
