Struct opendal::layers::FastraceLayer
source · pub struct FastraceLayer;
Available on crate feature
layers-fastrace
only.Expand description
Add fastrace for every operation.
§Examples
§Basic Setup
let _ = Operator::new(services::Memory::default())?
.layer(FastraceLayer)
.finish();
Ok(())
§Real usage
let reporter =
fastrace_jaeger::JaegerReporter::new("127.0.0.1:6831".parse()?, "opendal").unwrap();
fastrace::set_reporter(reporter, fastrace::collector::Config::default());
{
let root = Span::root("op", SpanContext::random());
let runtime = tokio::runtime::Runtime::new()?;
runtime.block_on(
async {
let _ = dotenvy::dotenv();
let op = Operator::new(services::Memory::default())?
.layer(FastraceLayer)
.finish();
op.write("test", "0".repeat(16 * 1024 * 1024).into_bytes())
.await?;
op.stat("test").await?;
op.read("test").await?;
Ok::<(), opendal::Error>(())
}
.in_span(Span::enter_with_parent("test", &root)),
)?;
}
fastrace::flush();
Ok(())
§Output
OpenDAL is using fastrace
for tracing internally.
To enable fastrace output, please init one of the reporter that fastrace
supports.
For example:
let reporter =
fastrace_jaeger::JaegerReporter::new("127.0.0.1:6831".parse()?, "opendal").unwrap();
fastrace::set_reporter(reporter, fastrace::collector::Config::default());
Ok(())
For real-world usage, please take a look at fastrace-datadog
or fastrace-jaeger
.
