<h3 id="provided-types"><a class="doc-anchor" href="#provided-types">§</a>Provided Types</h3>
<p>With no features enabled, this crate provides the <a href="struct.ArrayVec.html" title="struct tinyvec::ArrayVec"><code>ArrayVec</code></a> type, which
is an array-backed storage. You can push values into the array and pop them
out of the array and so on. If the array is made to overflow it will panic.</p>
<p>Similarly, there is also a <a href="struct.SliceVec.html" title="struct tinyvec::SliceVec"><code>SliceVec</code></a> type available, which is a vec-like
that’s backed by a slice you provide. You can add and remove elements, but
if you overflow the slice it will panic.</p>
<p>With the <code>alloc</code> feature enabled, the crate also has a <a href="enum.TinyVec.html" title="enum tinyvec::TinyVec"><code>TinyVec</code></a> type.
This is an enum type which is either an <code>Inline(ArrayVec)</code> or a <code>Heap(Vec)</code>.
If a <code>TinyVec</code> is <code>Inline</code> and would overflow it automatically transitions
itself into being <code>Heap</code> mode instead of a panic.</p>
<p>All of this is done with no <code>unsafe</code> code within the crate. Technically the
<code>Vec</code> type from the standard library uses <code>unsafe</code> internally, but <em>this
crate</em> introduces no new <code>unsafe</code> code into your project.</p>
<p>The limitation is that the element type of a vec from this crate must
support the <a href="https://doc.rust-lang.org/1.78.0/core/default/trait.Default.html" title="trait core::default::Default"><code>Default</code></a> trait. This means that this crate isn’t suitable for
all situations, but a very surprising number of types do support <code>Default</code>.</p>
<h3 id="other-features"><a class="doc-anchor" href="#other-features">§</a>Other Features</h3>
<ul>
<li><code>grab_spare_slice</code> lets you get access to the “inactive” portions of an
ArrayVec.</li>
<li><code>rustc_1_40</code> makes the crate assume a minimum rust version of <code>1.40.0</code>,
which allows some better internal optimizations.</li>
<li><code>serde</code> provides a <code>Serialize</code> and <code>Deserialize</code> implementation for
<a href="enum.TinyVec.html" title="enum tinyvec::TinyVec"><code>TinyVec</code></a> and <a href="struct.ArrayVec.html" title="struct tinyvec::ArrayVec"><code>ArrayVec</code></a> types, provided the inner item also has an
implementation.</li>
</ul>
<h3 id="api"><a class="doc-anchor" href="#api">§</a>API</h3>
<p>The general goal of the crate is that, as much as possible, the vecs here
should be a “drop in” replacement for the standard library <code>Vec</code> type. We
strive to provide all of the <code>Vec</code> methods with the same names and
signatures. The exception is that the element type of some methods will have
a <code>Default</code> bound that’s not part of the normal <code>Vec</code> type.</p>
<p>The vecs here also have a few additional methods that aren’t on the <code>Vec</code>
type. In this case, the names tend to be fairly long so that they are
unlikely to clash with any future methods added to <code>Vec</code>.</p>
<h3 id="stability"><a class="doc-anchor" href="#stability">§</a>Stability</h3>
<ul>
<li>The <code>1.0</code> series of the crate works with Rustc <code>1.34.0</code> or later, though
you still need to have Rustc <code>1.36.0</code> to use the <code>alloc</code> feature.</li>
<li>The <code>2.0</code> version of the crate is planned for some time after the
<code>min_const_generics</code> stuff becomes stable. This would greatly raise the
minimum rust version and also allow us to totally eliminate the need for
the <code>Array</code> trait. The actual usage of the crate is not expected to break
significantly in this transition.</li>
</ul>
