GitHub Actions’ matrix feature pairs naturally with cargo fc matrix to test feature combinations in parallel.

Approach 1 — fan out one job per combination#

First, a reusable workflow that computes the feature matrix:

# .github/workflows/feature-matrix.yaml
name: feature-matrix
on:
 workflow_call:
 outputs:
 matrix:
 description: "feature matrix"
 value: ${{ jobs.matrix.outputs.matrix }}
jobs:
 matrix:
 name: Generate feature matrix
 runs-on: ubuntu-24.04
 outputs:
 matrix: ${{ steps.compute-matrix.outputs.matrix }}
 steps:
 - uses: actions/checkout@v4
 - uses: romnn/cargo-feature-combinations@main
 - name: Compute feature matrix
 id: compute-matrix
 run: |-
 MATRIX="$(cargo fc matrix)"
 echo "${MATRIX}"
 echo "matrix=${MATRIX}" >> "$GITHUB_OUTPUT"

Then consume it to build every combination in parallel:
