<h2 id="comparing-levels"><a href="#comparing-levels">Comparing Levels</a></h2>
<p><code>Level</code> implements the <a href="https://doc.rust-lang.org/nightly/core/cmp/trait.PartialOrd.html" title="PartialOrd"><code>PartialOrd</code></a> and <a href="https://doc.rust-lang.org/nightly/core/cmp/trait.Ord.html" title="Ord"><code>Ord</code></a> traits, allowing two
<code>Level</code>s to be compared to determine which is considered more or less
verbose. Levels which are more verbose are considered “greater than” levels
which are less verbose, with <a href="../struct.Level.html#associatedconstant.ERROR" title="Level::ERROR"><code>Level::ERROR</code></a> considered the lowest, and
<a href="../struct.Level.html#associatedconstant.TRACE" title="Level::TRACE"><code>Level::TRACE</code></a> considered the highest.</p>
<p>For example:</p>
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>tracing_core::Level;
<span class="macro">assert!</span>(Level::TRACE &gt; Level::DEBUG);
<span class="macro">assert!</span>(Level::ERROR &lt; Level::WARN);
<span class="macro">assert!</span>(Level::INFO &lt;= Level::DEBUG);
<span class="macro">assert_eq!</span>(Level::TRACE, Level::TRACE);</code></pre></div>
<h2 id="filtering"><a href="#filtering">Filtering</a></h2>
<p><code>Level</code>s are typically used to implement filtering that determines which
spans and events are enabled. Depending on the use case, more or less
verbose diagnostics may be desired. For example, when running in
development, <a href="../struct.Level.html#associatedconstant.DEBUG"><code>DEBUG</code></a>-level traces may be enabled by default. When running in
production, only <a href="../struct.Level.html#associatedconstant.INFO"><code>INFO</code></a>-level and lower traces might be enabled. Libraries
may include very verbose diagnostics at the <a href="../struct.Level.html#associatedconstant.DEBUG"><code>DEBUG</code></a> and/or <a href="../struct.Level.html#associatedconstant.TRACE"><code>TRACE</code></a> levels.
Applications using those libraries typically chose to ignore those traces. However, when
debugging an issue involving said libraries, it may be useful to temporarily
enable the more verbose traces.</p>
<p>The <a href="../struct.LevelFilter.html" title="LevelFilter"><code>LevelFilter</code></a> type is provided to enable filtering traces by
verbosity. <code>Level</code>s can be compared against <a href="../struct.LevelFilter.html" title="LevelFilter"><code>LevelFilter</code></a>s, and
<a href="../struct.LevelFilter.html" title="LevelFilter"><code>LevelFilter</code></a> has a variant for each <code>Level</code>, which compares analogously
to that level. In addition, <a href="../struct.LevelFilter.html" title="LevelFilter"><code>LevelFilter</code></a> adds a <a href="../struct.LevelFilter.html#associatedconstant.OFF" title="LevelFilter::OFF"><code>LevelFilter::OFF</code></a>
variant, which is considered “less verbose” than every other <code>Level</code>. This is
intended to allow filters to completely disable tracing in a particular context.</p>
<p>For example:</p>
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>tracing_core::{Level, LevelFilter};
<span class="macro">assert!</span>(LevelFilter::OFF &lt; Level::TRACE);
<span class="macro">assert!</span>(LevelFilter::TRACE &gt; Level::DEBUG);
<span class="macro">assert!</span>(LevelFilter::ERROR &lt; Level::WARN);
<span class="macro">assert!</span>(LevelFilter::INFO &lt;= Level::DEBUG);
<span class="macro">assert!</span>(LevelFilter::INFO &gt;= Level::INFO);</code></pre></div>
<h3 id="examples"><a href="#examples">Examples</a></h3>
<p>Below is a simple example of how a <a href="../trait.Subscriber.html"><code>Subscriber</code></a> could implement filtering through
a <a href="../struct.LevelFilter.html" title="LevelFilter"><code>LevelFilter</code></a>. When a span or event is recorded, the <a href="../trait.Subscriber.html#tymethod.enabled"><code>Subscriber::enabled</code></a> method
compares the span or event’s <code>Level</code> against the configured <a href="../struct.LevelFilter.html" title="LevelFilter"><code>LevelFilter</code></a>.
The optional <a href="../trait.Subscriber.html#method.max_level_hint"><code>Subscriber::max_level_hint</code></a> method can also be implemented to allow spans
and events above a maximum verbosity level to be skipped more efficiently,
often improving performance in short-lived programs.</p>
<div class="example-wrap"><pre class="rust rust-example-rendered"><code><span class="kw">use </span>tracing_core::{span, Event, Level, LevelFilter, Subscriber, Metadata};

<p>It is worth noting that the <code>tracing-subscriber</code> crate provides <a href="https://docs.rs/tracing-subscriber/latest/tracing_subscriber/filter/struct.EnvFilter.html">additional
APIs</a> for performing more sophisticated filtering, such as
enabling different levels based on which module or crate a span or event is
recorded in.</p>
