Function compiler_version

prqlc/prqlc/src/lib.rs:142–169

Get the version of the compiler. This is determined by the first of: - An optional environment variable `PRQL_VERSION_OVERRIDE`; primarily useful for internal testing. - Note that this env var is checked on every call of this function. Without checking each read, we found some internal tests were flaky. If this caused any perf issues, we could adjust the tests that rely on versions to run in a mor
