# Verify that individual crates build with various feature combinations
#
# re: https://github.com/tikv/tikv/issues/9406
#
# TiKV has several compile time features that are threaded through the
# dependency tree. It is common that the features are not configured correctly,
# causing individual crates to not build on their own. This script goes through
# each individual crate and runs `cargo check -p` and `cargo test -p --no-run`
# on them using their default feature sets.
#
# Requires Python 3.6+
