<div class="sectionbody">
<div class="paragraph">
<p>Given a <em>SPEC</em> argument, print out the fully qualified package ID specifier
for a package or dependency in the current workspace. This command will
generate an error if <em>SPEC</em> is ambiguous as to which package it refers to in
the dependency graph. If no <em>SPEC</em> is given, then the specifier for the local
package is printed.</p>
</div>
<div class="paragraph">
<p>This command requires that a lockfile is available and dependencies have been
fetched.</p>
</div>
<div class="paragraph">
<p>A package specifier consists of a name, version, and source URL. You are
allowed to use partial specifiers to succinctly match a specific package as
long as it matches only one package. The format of a <em>SPEC</em> can be one of the
following:</p>

<p>Path to the <code>Cargo.toml</code> file. By default, Cargo searches in the current

<dd>
<p>Either of these flags requires that the <code>Cargo.lock</code> file is
up-to-date. If the lock file is missing, or it needs to be updated, Cargo will
exit with an error. The <code>--frozen</code> flag also prevents Cargo from
attempting to access the network to determine if it is out-of-date.</p>
<div class="paragraph">
<p>These may be used in environments where you want to assert that the
<code>Cargo.lock</code> file is up-to-date (such as a CI build) or want to avoid network
access.</p>
</div>
</dd>
<dt class="hdlist1"><strong>--offline</strong></dt>
<dd>
<p>Prevents Cargo from accessing the network for any reason. Without this
flag, Cargo will stop with an error if it needs to access the network and
the network is not available. With this flag, Cargo will attempt to
proceed without the network if possible.</p>
<div class="paragraph">
<p>Beware that this may result in different dependency resolution than online
mode. Cargo will restrict itself to crates that are downloaded locally, even
if there might be a newer version as indicated in the local copy of the index.
See the <a href="commands/cargo-fetch.html">cargo-fetch(1)</a> command to download dependencies before going
offline.</p>
