What is the format tracing-flame's textual representation?

[byte-sourcerer]

I would like to generate the flaming graph by using tracing-flame-0.2.0, but the result is weird. I would like to know the text format of it, so I can figure out whether it's a bug of tracing-flame🤔.

The text is like:

ThreadId(18) 216575291
ThreadId(18);A::B::C::put_batch 16042
ThreadId(18);A::B::C::put_batch;A::D::transaction::write_batch 294917
ThreadId(18);A::B::C::put_batch 4625
ThreadId(18);A::B::C::put_batch;A::D::transaction::commit 1875
ThreadId(18);A::B::C::put_batch 2083
ThreadId(18) 17163333
ThreadId(18);A::B::C::put_batch 959
ThreadId(18);A::B::C::put_batch;A::D::transaction::commit 12291
ThreadId(18);A::B::C::put_batch;A::D::transaction::commit;A::state::states::write_batch 7667
ThreadId(18);A::B::C::put_batch;A::D::transaction::commit 708
ThreadId(18);A::B::C::put_batch 459
...

the flamegraph I generated is:

How did you generate the flamegraph? Using inferno (https://github.com/tokio-rs/tracing/tree/master/tracing-flame#generating-the-image)?
