Function build_script 

pub fn build_script(
    dialect: Dialect,
    schema: &Schema,
    plan: &SeedPlan,
    max_params: Option<usize>,
) -> Result<SeedScript, CliError>

Builds the seed script for schema in dialect.

max_params caps the values per INSERT (D1’s HTTP API limits statement length, so its driver passes a lower cap).

Errors

Returns CliError when this build has no driver for dialect, a table or column name in plan is unknown, or seeding fails (for example a foreign-key cycle).
