Rayon filtering

6

I recently went to parallelize/optimize a library with `rayon`, and my flamegraph (unsurprisingly!) became absolutely unreadable. Optionally filtering out rayon symbols/functions would be a super helpful feature

It would be nice if we have line numbers. In which case I can differetiate multiple function calls in the same caller. Arranging functions by line numbers is also possible....

Flamegraph generation memory usage is quite high for large inputs

7

Memory usage for `inferno-flamegraph`, and the equivalent Rust API usage, is proportional to input file size. A 44MB file results in 60MB memory usage for me, a 3KB input file...

Tidy up library interface for flamegraph (and collapse?)

14

If we want other projects, like @koute's [nperf](https://github.com/nokia/nperf), to [start using](https://www.reddit.com/r/rust/comments/ak6s89/porting_flamegraph_to_rust_video/ef6h7il/) inferno to draw their flame graphs (and perhaps even to do the collapsing), we need to provide an external...

Should not collapse adjacent equivalently-named stacks in flame chart mode

For example, with the input of ``` a;b 1 a;b 1 a 0 ``` I would expect 3 nodes in the output: * `a` with width 2 * `b` with...

Option for true "start" for nodes

Currently, inferno, even in flame chart mode, doesn't really support passing in start time and end time (rather than just a count). This means that you can't get output like...

The upstream FlameGraph project has a number of outstanding [pull requests](https://github.com/brendangregg/FlameGraph/pulls) that fix bugs and add or improve features. We should take a look through them and see whether we...

"offwaketime" output causes 'attempt to multiply with overflow'

Worth noting btw, initially I have built it in release, and it has shown just invalid top-half of stacktraces. [Related report on vanilla flamegraph](https://github.com/brendangregg/FlameGraph/issues/233) ## Steps to reproduce 1. Make...

Hi-Angel

Test results show same size for all stack frames

API for creating flamegraphs that isn't tied to strings

Hi, I am attempting to embed source code in my flamegraphs, basically to have inline tracebacks/callstacks, and... it's a little tricky. The requirement for text formatting means I need to...
