use in conjunction with a <code>tracing</code><code>Subscriber</code> to consume events from
dependencies that emit <ahref="../../log/index.html"title="mod log"><code>log</code></a> records within a trace context.</p>
<p>To create and initialize a <code>LogTracer</code> with the default configurations, use:</p>
<ul>
<li><ahref="LogTracer.html#method.init"><code>init</code></a> if you want to convert all logs, regardless of log level,
allowing the tracing <code>Subscriber</code> to perform any filtering</li>
<li><ahref="LogTracer.html#method.init_with_filter"><code>init_with_filter</code></a> to convert all logs up to a specified log level</li>
</ul>
<p>In addition, a <ahref="../struct.LogTracer.html#method.builder"title="associated function tracing_log::LogTracer::builder">builder</a> is available for cases where more advanced
configuration is required. In particular, the builder can be used to <ahref="struct.Builder.html#method.ignore_crate"title="method tracing_log::log_tracer::Builder::ignore_crate">ignore
