Struct PreparedStatement 

pub struct PreparedStatement { /* private fields */ }

A prepared statement handle with pre-computed statement name. This eliminates per-query hash computation and HashMap lookup. Create once, execute many times.

Example

// Prepare once (compute hash + register with PostgreSQL)
let stmt = conn.prepare("SELECT id, name FROM users WHERE id = $1").await?;
// Execute many times (no hash, no lookup!)
for id in 1..1000 {
    conn.execute_prepared(&stmt, &[Some(id.to_string().into_bytes())]).await?;
}

Implementations

impl PreparedStatement

pub fn from_sql_bytes(sql_bytes: &[u8]) -> Self

Create a new prepared statement handle from SQL bytes. This hashes the SQL bytes directly without String allocation.

pub fn from_sql(sql: &str) -> Self

Create from SQL string (convenience method).

pub fn name(&self) -> &str

Get the statement name.
