clawhdf5/scripts/ci-test.sh

#!/usr/bin/env bash
# CI test script — runs fmt, clippy (all targets + feature matrix), tests,
# Python interop suites, bench compilation, and no_std checks.
#
# Usage:
#   ./scripts/ci-test.sh
#
# Environment:
#   CLAWHDF5_REQUIRE_INTEROP=1  Fail (instead of skip) when python3 with
#                               h5py/netCDF4/xarray is missing, or without
#                               maturin/pytest for the Python package step.
#                               CI sets this.
#                               Unset locally, the interop steps are skipped
#                               if python3+h5py is not importable.
#   CLAWHDF5_FUZZ_SECONDS=N     Run each cargo-fuzz target for N seconds
#                               (needs nightly + cargo-fuzz). Default: skip.
#
# Exit codes:
#   0 — all checks passed
#   1 — one or more checks failed
