Module refresh 

REFRESH MATERIALIZED VIEW statements for PostgreSQL.

Build the statement with refresh_materialized_view or RefreshMaterializedView::new and run it with a driver’s execute(...), which accepts any ToSQL value.

Examples

use drizzle_postgres::builder::refresh::RefreshMaterializedView;
use drizzle_core::ToSQL;

// `user_stats` stands for a materialized view defined with `#[PostgresView]`.
let refresh = RefreshMaterializedView::new(&user_stats);
assert_eq!(refresh.to_sql().sql(), r#"REFRESH MATERIALIZED VIEW "user_stats""#);

// Keep the view readable while it refreshes (needs a unique index).
let refresh = RefreshMaterializedView::new(&user_stats).concurrently();
assert_eq!(
    refresh.to_sql().sql(),
    r#"REFRESH MATERIALIZED VIEW CONCURRENTLY "user_stats""#
);

// Empty the view; it cannot be queried until refreshed again.
let refresh = RefreshMaterializedView::new(&user_stats).with_no_data();
assert_eq!(
    refresh.to_sql().sql(),
    r#"REFRESH MATERIALIZED VIEW "user_stats" WITH NO DATA"#
);
