<p>A collection ID is a globally unique identifier which, if set, is used to
identify refs from a repository which are mirrored elsewhere, such as in
mirror repositories or peer to peer networks.</p>
<p>This is separate from the <code class="literal">collection-id</code> configuration key for a remote, which
is used to store the collection ID of the repository that remote points to.</p>
<p>The collection ID should only be set on an <a class="link" href="ostree-Content-addressed-object-store.html#OstreeRepo" title="OstreeRepo"><span class="type">OstreeRepo</span></a> if it is the canonical
collection for some refs.</p>
<p>A collection ID must be a reverse DNS name, where the domain name is under the
control of the curator of the collection, so they can demonstrate ownership
of the collection. The later elements in the reverse DNS name can be used to
disambiguate between multiple collections from the same curator. For example,
<code class="literal">org.exampleos.Main</code> and <code class="literal">org.exampleos.Apps</code>. For the complete format of
collection IDs, see <code class="function">ostree_validate_collection_id()</code>.</p>

* @title: Bloom filter
* @short_description: Bloom filter implementation supporting building and
* reading filters
* @stability: Unstable
* @include: libostree/ostree-bloom-private.h
*
* #OstreeBloom is an implementation of a bloom filter which supports writing to
* and loading from a #GBytes bit array. The caller must store metadata about
* the bloom filter (its hash function and `k` parameter value) separately, as
* the same values must be used when reading from a serialised bit array as were
* used to build the array in the first place.
*
* This is a standard implementation of a bloom filter, and background reading
* on the theory can be
* [found on Wikipedia](https://en.wikipedia.org/wiki/Bloom_filter). In
* particular, a bloom filter is parameterised by `m` and `k` parameters: the
* size of the bit array (in bits) is `m`, and the number of hash functions
* applied to each element is `k`. Bloom filters require a universal hash
* function which can be parameterised by `k`. We have #OstreeBloomHashFunc,
* with ostree_str_bloom_hash() being an implementation for strings.
*
* The serialised output from a bloom filter is guaranteed to be stable across
* versions of libostree as long as the same values for `k` and the hash
* function are used.
*
* #OstreeBloom is mutable when constructed with ostree_bloom_new(), and elements
* can be added to it using ostree_bloom_add_element(), until ostree_bloom_seal()
* is called to serialise it and make it immutable. After then, the bloom filter
* can only be queried using ostree_bloom_maybe_contains().
*
* If constructed with ostree_bloom_new_from_bytes(), the bloom filter is
* immutable from construction, and can only be queried.
*
