Crate use_db_column 

use-db-column

Column references, type labels, defaults, nullability, ordinals, and metadata.

This crate is part of the use-database facade workspace. It provides small, engine-neutral vocabulary types and metadata containers. It does not connect to databases, execute queries, run migrations, parse SQL, or model engine-specific behavior.

Example

use use_db_column::{ColumnRef, ColumnTypeLabel};
use use_db_name::ColumnName;

let column = ColumnRef::new(ColumnName::new("id").expect("valid column"));
let label = ColumnTypeLabel::new("uuid").expect("valid type label");

assert_eq!(column.column().as_str(), "id");
assert_eq!(label.as_str(), "uuid");
