<p><code>Level</code> implements the <ahref="https://doc.rust-lang.org/1.80.0/core/cmp/trait.PartialOrd.html"title="trait core::cmp::PartialOrd"><code>PartialOrd</code></a> and <ahref="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 <ahref="struct.Level.html#associatedconstant.ERROR"title="associated constant tracing::Level::ERROR"><code>Level::ERROR</code></a> considered the lowest, and
<ahref="struct.Level.html#associatedconstant.TRACE"title="associated constant tracing::Level::TRACE"><code>Level::TRACE</code></a> considered the highest.</p>
<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, <ahref="struct.Level.html#associatedconstant.DEBUG"title="associated constant tracing::Level::DEBUG"><code>DEBUG</code></a>-level traces may be enabled by default. When running in
production, only <ahref="struct.Level.html#associatedconstant.INFO"title="associated constant tracing::Level::INFO"><code>INFO</code></a>-level and lower traces might be enabled. Libraries
may include very verbose diagnostics at the <ahref="struct.Level.html#associatedconstant.DEBUG"title="associated constant tracing::Level::DEBUG"><code>DEBUG</code></a> and/or <ahref="struct.Level.html#associatedconstant.TRACE"title="associated constant tracing::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 <ahref="level_filters/struct.LevelFilter.html"title="struct tracing::level_filters::LevelFilter"><code>LevelFilter</code></a> type is provided to enable filtering traces by
verbosity. <code>Level</code>s can be compared against <ahref="level_filters/struct.LevelFilter.html"title="struct tracing::level_filters::LevelFilter"><code>LevelFilter</code></a>s, and
<ahref="level_filters/struct.LevelFilter.html"title="struct tracing::level_filters::LevelFilter"><code>LevelFilter</code></a> has a variant for each <code>Level</code>, which compares analogously
to that level. In addition, <ahref="level_filters/struct.LevelFilter.html"title="struct tracing::level_filters::LevelFilter"><code>LevelFilter</code></a> adds a <ahref="level_filters/struct.LevelFilter.html#associatedconstant.OFF"title="associated constant tracing::level_filters::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>Below is a simple example of how a <ahref="trait.Subscriber.html"title="trait tracing::Subscriber"><code>Subscriber</code></a> could implement filtering through
a <ahref="level_filters/struct.LevelFilter.html"title="struct tracing::level_filters::LevelFilter"><code>LevelFilter</code></a>. When a span or event is recorded, the <ahref="trait.Subscriber.html#tymethod.enabled"title="method tracing::Subscriber::enabled"><code>Subscriber::enabled</code></a> method
compares the span or event’s <code>Level</code> against the configured <ahref="level_filters/struct.LevelFilter.html"title="struct tracing::level_filters::LevelFilter"><code>LevelFilter</code></a>.
The optional <ahref="trait.Subscriber.html#method.max_level_hint"title="method tracing::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>
<p>It is worth noting that the <code>tracing-subscriber</code> crate provides <ahref="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
