We had a ton of issues around `TexturesDelta` that weren't properly applied because we early-out of some function: * https://github.com/emilk/egui/pull/8313 * https://github.com/emilk/egui/pull/8250 * https://github.com/emilk/egui/pull/8279 This PR changes texture updates, so that we always store them after taking them out of `FullOutput` and keep the delta around until it's actually applied (by passing &mut refs and draining instead of iterating). So even if we add a new early return somewhere, that can't break texture updates. It also optimizes `TexturesDelta::append` by dropping any previous deltas if there's a new `whole` delta or a `free`. It also adds a debug assert that any `TexturesDelta` is empty when dropped, as an additional safeguard in case the bug sneaks back in. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
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
eguiapi. - To remove the amount of code in
eguiproper. - To make it easy for 3rd party egui integrations to use it for tests.
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"
