Struct TypeBinding 

pub struct TypeBinding {
    pub schema_name: String,
    pub field_to_column: Vec<usize>,
}

Mapping from TypeSchema field indices to Arrow column indices.

Used for O(1) field→column resolution when accessing DataTable columns through a typed view.

Fields

schema_name: String

The type name this binding is for.

field_to_column: Vec<usize>

Maps TypeSchema field index → Arrow column index.
