You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/prisma-engines/query-engine/dmmf/src
    
    the code of the file until where you have to start completion: mod ast_builders;
mod serialization_ast;

#[cfg(test)]
mod tests;

pub use serialization_ast::DataModelMetaFormat;

use ast_builders::schema_to_dmmf;
use schema::
    
pub fn from_precomputed_parts(query_schema: &QuerySchema) -> DataModelMetaFormat {
    let data_model = schema_to_dmmf(&query_schema.internal_data_model.schema);
    let (schema, mappings) = ast_builders::render(query_schema);

    DataModelMetaFormat {
        data_model,
        schema,
        mappings,
    }
}
