Compiles the Polars Rust engine behind polars[rtcompat] as a cp310-abi3 extension. Upstream publishes no riscv64 wheel.

Mirrors upstream's release-python.yml, which builds all three runtimes from one matrix, so compat joins polars-runtime-32/-64 in build-polars-runtime.yml instead of getting its own workflow.

Differs from upstream

  • Same riscv64 changes as polars-runtime-32/-64: manylinux 2_39, reduced LTO/codegen, fewer build jobs.
  • Compat-only flags (target-feature, allocator="default") are x86-64-only upstream, so none apply on riscv64.

Testing

  • same as upstream

License: OK

Built on cp312.

Build polars-runtime-compat alongside polars-runtime-32/-64 in build-polars-runtime.yml, the way upstream's release-python.yml builds all three runtimes from one matrix. Upstream only sets compat-specific flags for x86-64, so on riscv64 the build differs from the other runtimes only by its manifest path.
