pub struct SchemaResult {
pub columns: Vec<ColumnSchema>,
pub rows_sampled: usize,
pub inference_time_ms: u128,
pub schema_stable: bool,
}Expand description
Result of fast schema inference — column names paired with inferred data types.
Fields§
§columns: Vec<ColumnSchema>Columns with their inferred types. For CSV/Parquet the order matches the source; for JSON/JSONL columns are sorted alphabetically.
rows_sampled: usizeHow many rows were sampled to infer the schema (0 for Parquet metadata).
inference_time_ms: u128Time taken for inference in milliseconds.
schema_stable: booltrue when the entire file was consumed or schema was read from
metadata; false when inference stopped at the sample-size cap and
the schema may not have fully stabilized.
