# Summary
This method strips a long type name like `bevy::render:📷:PerspectiveCameraBundle` down into the bare type name (`PerspectiveCameraBundle`). This is generally useful utility method, needed by #4299 and #5121.
As a result:
- This method was moved to `bevy_utils` for easier reuse.
- The legibility and robustness of this method has been significantly improved.
- Harder test cases have been added.
This change was split out of #4299 to unblock it and make merging / reviewing the rest of those changes easier.
## Changelog
- added `bevy_utils::get_short_name`, which strips the path from a type name for convenient display.
- removed the `TypeRegistry::get_short_name` method. Use the function in `bevy_utils` instead.
# Objective
- Have an easy way to compare spans between executions
## Solution
- Add a tool to compare spans from chrome traces
```bash
> cargo run --release -p spancmp -- --help
Compiling spancmp v0.1.0
Finished release [optimized] target(s) in 1.10s
Running `target/release/spancmp --help`
spancmp
USAGE:
spancmp [OPTIONS] <TRACE> [SECOND_TRACE]
ARGS:
<TRACE>
<SECOND_TRACE>
OPTIONS:
-h, --help Print help information
-p, --pattern <PATTERN> Filter spans by name matching the pattern
-t, --threshold <THRESHOLD> Filter spans that have an average shorther than the threshold
[default: 0]
```
for each span, it will display the count, minimum duration, average duration and max duration. It can be filtered by a pattern on the span name or by a minimum average duration.
