Function compile_haskell 

pub fn compile_haskell(
    source: &str,
    target: &str,
    include: &[&Path],
) -> Result<CompileResult, CompileError>

Compiles Haskell source code to Tidepool Core at runtime.

This function shells out to tidepool-extract (which must be available on the system $PATH) to perform GHC parsing, type-checking, and Core translation. It writes the source to a temporary file, executes the extractor, and reads back the resulting CBOR and metadata.

Compiled results are cached in the XDG cache directory (typically ~/.cache/tidepool) to speed up repeated compilations. The cache key is derived from the source code, the target binder, and a fingerprint of any included dependency directories.

Arguments

• source - The Haskell source code to compile.
• target - The name of the top-level binder to use as the entry point (e.g., “main”).
• include - Paths to directories containing Haskell modules to include in the search path.

Returns

• Ok((CoreExpr, DataConTable)) on success.
• Err(CompileError) if compilation fails, the extractor is missing, or output is invalid.
