Crate use_pg_column 

use-pg-column

PostgreSQL column metadata primitives for RustUse.

This crate provides column names, column type metadata, default-expression labels, nullability, generated-column labels, and identity labels. Defaults are stored as labels and are not parsed or executed.

Example

use use_pg_column::{PgColumn, PgColumnDefault, PgColumnName, PgIdentityKind, PgNullability};
use use_pg_type::PgBuiltInType;

let column = PgColumn::with_built_in_type(PgColumnName::new("id")?, PgBuiltInType::BigInt)
    .with_nullability(PgNullability::NotNull)
    .with_identity(PgIdentityKind::Always)
    .with_default(PgColumnDefault::new("nextval('users_id_seq')")?);

assert_eq!(column.name().as_str(), "id");
assert_eq!(column.type_name().as_str(), "bigint");
assert_eq!(column.nullability(), PgNullability::NotNull);
