Emil Ernerfeldt 7216d0e386 Use mimalloc for benchmarks (#7029 ) `mimalloc` is a _much_ faster allocator, especially important when doing a lot of small allocations (which egui does). We use `mimalloc` in Rerun, and I recommend everyone to use it. ## The difference it makes ![image](https://github.com/user-attachments/assets/b22e0025-bc5e-4b3c-94e0-74ce46e86f85)		2025-05-06 17:54:06 +02:00

`egui` demo library

This crate contains example code for egui.

The demo library is a separate crate for three reasons:

To ensure it only uses the public egui api.
To remove the amount of code in egui proper.
To make it easy for 3rd party egui integrations to use it for tests.
- See for instance https://github.com/not-fl3/egui-miniquad/blob/master/examples/demo.rs

This crate also contains benchmarks for egui. Run them with

# Run all benchmarks
cargo bench -p egui_demo_lib 

# Run a single benchmark
cargo bench -p egui_demo_lib "benchmark name"

# Profile benchmarks with cargo-flamegraph (--root flag is necessary for MacOS)
CARGO_PROFILE_BENCH_DEBUG=true cargo flamegraph --bench benchmark --root -p egui_demo_lib  -- --bench "benchmark name"

# Profile with cargo-instruments
CARGO_PROFILE_BENCH_DEBUG=true cargo instruments --profile bench --bench benchmark -p egui_demo_lib -t time -- --bench "benchmark name"
