Function dump 

pub fn dump(
    script_name: &str,
    type_check: Option<&TypeCheckState>,
    state: SessionRef<'_>,
) -> Result<Vec<u8>, Error>

Available on crate features code and embedded-python only.

Serializes a live session and its metadata into a versioned dump, readable by Dump::load.

Takes the state by reference because dumping is read-only: the caller keeps its session and can carry on feeding it.

Errors

Returns an error if serialization fails.
