Struct OwnedPreparedStatement 

pub struct OwnedPreparedStatement { /* private fields */ }

Owned PostgreSQL prepared statement wrapper.

This is the owned counterpart to PreparedStatement that doesn’t have any lifetime constraints. All data is owned by this struct, making it suitable for long-term storage, caching, or passing across thread boundaries.

Use Cases

• Caching: Store prepared statements in a cache for reuse
• Multi-threading: Pass prepared statements between threads (with tokio-postgres)
• Long-term storage: Keep prepared statements in application state
• Query reuse: Execute the same query with different parameters efficiently

Examples

// Create a query and convert to SQL
let query = builder.select(user.name).from(user);
let sql = query.to_sql();

// In practice, the driver creates a PreparedStatement from the SQL
// let prepared = driver.prepare(sql)?;
// let owned: OwnedPreparedStatement = prepared.into_owned();
// Owned can be stored in a HashMap for reuse

Conversion

You can convert between borrowed and owned forms:

• PreparedStatement::into_owned() → OwnedPreparedStatement
• OwnedPreparedStatement → PreparedStatement (via From trait)
