<h2 id="comparing-levels"><a class="doc-anchor" href="#comparing-levels">§</a>Comparing Levels</h2>
<p><code>Level</code> implements the <a href="https://doc.rust-lang.org/1.80.0/core/cmp/trait.PartialOrd.html" title="trait core::cmp::PartialOrd"><code>PartialOrd</code></a> and <a href="https://doc.rust-lang.org/1.80.0/core/cmp/trait.Ord.html" title="trait core::cmp::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="associated constant tracing_core::Level::ERROR"><code>Level::ERROR</code></a> considered the lowest, and
<a href="struct.Level.html#associatedconstant.TRACE" title="associated constant tracing_core::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 class="doc-anchor" href="#filtering">§</a>Filtering</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" title="associated constant tracing_core::Level::DEBUG"><code>DEBUG</code></a>-level traces may be enabled by default. When running in
production, only <a href="struct.Level.html#associatedconstant.INFO" title="associated constant tracing_core::Level::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" title="associated constant tracing_core::Level::DEBUG"><code>DEBUG</code></a> and/or <a href="struct.Level.html#associatedconstant.TRACE" title="associated constant tracing_core::Level::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="struct tracing_core::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="struct tracing_core::LevelFilter"><code>LevelFilter</code></a>s, and
<a href="struct.LevelFilter.html" title="struct tracing_core::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="struct tracing_core::LevelFilter"><code>LevelFilter</code></a> adds a <a href="struct.LevelFilter.html#associatedconstant.OFF" title="associated constant tracing_core::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 class="doc-anchor" href="#examples">§</a>Examples</h3>
<p>Below is a simple example of how a <a href="trait.Subscriber.html" title="trait tracing_core::Subscriber"><code>Subscriber</code></a> could implement filtering through
a <a href="struct.LevelFilter.html" title="struct tracing_core::LevelFilter"><code>LevelFilter</code></a>. When a span or event is recorded, the <a href="trait.Subscriber.html#tymethod.enabled" title="method tracing_core::Subscriber::enabled"><code>Subscriber::enabled</code></a> method
compares the span or events <code>Level</code> against the configured <a href="struct.LevelFilter.html" title="struct tracing_core::LevelFilter"><code>LevelFilter</code></a>.
The optional <a href="trait.Subscriber.html#method.max_level_hint" title="method tracing_core::Subscriber::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>
