Field type and characteristics

Examples

use copybook_core::FieldKind;

let alpha = FieldKind::Alphanum { len: 10 };
assert!(matches!(alpha, FieldKind::Alphanum { len: 10 }));

let packed = FieldKind::PackedDecimal { digits: 7, scale: 2, signed: true };
assert!(matches!(packed, FieldKind::PackedDecimal { signed: true, .. }));

let group = FieldKind::Group;
assert!(matches!(group, FieldKind::Group));

Variants
