Module structs 

GPU-accelerated struct column operations.

Provides operations on struct (nested) columns, such as extracting child columns by index.

Examples

use cudf::Column;

// Struct columns are created via I/O readers (Parquet, JSON)
// or the Arrow interop interface.
// let struct_col: Column = /* from parquet/json/arrow */;
// let child = struct_col.structs_extract(0).unwrap();
