boost::dynamic_bitset::is_subset_of :: Boost.DynamicBitset

# boost::dynamic_bitset::is_subset_of

Checks whether `*this` is a subset of `b`.

## Synopsis

Declared in `<boost/dynamic_bitset/dynamic_bitset.hpp>`

    bool
    is_subset_of(dynamic_bitset const& b) const;

## Return Value

`true` if this bitset is a subset of bitset `b`. That is, it returns `true` if, for every bit that is set in this bitset, the corresponding bit in bitset `b` is also set. Otherwise this function returns `false`.

## Parameters

Name | Description
--- | ---
b | The bitset to test `*this` against.

## Preconditions

- `this‐>size() == b.size()`.
