AndroidX Collection Benchmarks for Native Platforms

This directory builds a set of benchmarks for AndroidX Collection on native platforms. Currently only macOS (x86_64) is supported.

To build, run in the collection project root:

./gradlew --no-configuration-cache -Pandroidx.github.build=true :collection:collection-benchmark-native:assemble

Then execute the resulting binary at:

../../out/androidx/collection/collection-benchmark-native/build/exe/main/debug/collection-benchmark-native

The output will look something like this:
