Tracing Sample

(Named such because tracingcrate disambiguation didn't work with cargo run -p tracing:0.0.0.)

Running

cargo run -p tracing-sample

Rendering

You can render the information logged into ./tracing-sample.folded into SVG images using inferno-flamegraph (cargo install inferno).

Flamegraph

#!/bin/sh
cat tracing-sample.folded | inferno-flamegraph > flamegraph.svg

#!/bin/nu
open --raw tracing-sample.folded | inferno-flamegraph --flamechart | save flamechart.svg

Flamechart

#!/bin/sh
cat tracing-sample.folded | inferno-flamegraph --flamechart > flamechart.svg

#!/bin/nu
open --raw tracing-sample.folded | inferno-flamegraph --flamechart | save flamechart.svg

Any parameter that is None, for example because it is optional and wasn't set, is not reported.

Sample Output

In addition to text passed through the output streams, a file with timing information is generated (using tracing-flame):
