Function compiler_version_str

prqlc/prqlc/src/cli/mod.rs:98–101

This seems to be required because passing `compiler_version()` directly to `command` fails because it's not a string, and we can't seem to convert it to a string inline.

/// `command` fails because it's not a string, and we can't seem to convert it

pub fn compiler_version_str() -> &'static str {
    static COMPILER_VERSION: std::sync::OnceLock<String> = std::sync::OnceLock::new();
    COMPILER_VERSION.get_or_init(|| compiler_version().to_string())
}
