Function infer_csv_schema 

Source 
pub fn infer_csv_schema(
    csv_text: &str,
    has_header: bool,
) -> Result<Vec<ColumnSchema>, McpError>
Expand description

Infer a ColumnSchema for each CSV column (Tier 3).

When has_header is true, the first row provides column names; otherwise columns are named col_0, col_1, etc. Up to 1 000 data rows are sampled to determine types. All CSV columns are marked nullable because CSV has no way to express a NOT NULL constraint.

§Errors

  • Returns ErrorCode::SchemaMismatch when the CSV header line or any sampled record cannot be parsed.
  • Returns ErrorCode::EmptyData when there are no data rows (to infer column count in the headerless case) or when the header row is empty.
