# Runs the feature/target combinations CI runs, locally, in one command.
#
# CI's matrix is wider than the obvious "default + all features": in particular
# it builds with `bundled-test` *without* `duckdb-1-5`, and it compiles the lib
# for `wasm32-unknown-emscripten`. Both caught defects that every other
# combination compiled through:
#
#   - a `#[test]` calling a `duckdb-1-5`-gated method with no `cfg` gate breaks
#     `--features bundled-test` alone and nothing else;
#   - `1 << 37` in a `usize` const is a const-eval overflow only where pointers
#     are 32 bits, i.e. wasm32 — a target DuckDB's own extension CI builds.
#
# Usage:
#   scripts/check-matrix.sh            # compile checks + lints (fast)
#   scripts/check-matrix.sh --tests    # ...and run the test suites (slow, needs disk)
#
# The wasm32 legs are skipped with a notice if the target is not installed:
#   rustup target add wasm32-unknown-emscripten

# CI sets these globally, which promotes every warning to an error. Without
