sentinel-driver

High-performance PostgreSQL wire protocol driver for Rust.

• PG-only — no multi-database abstraction tax
• Pipeline mode — automatic query batching (PG 14+)
• Binary encoding — 15-40% faster for non-text types
• Zero-copy — bytes::Bytes slices for large column values
• SCRAM-SHA-256 — correct SASLprep implementation
• COPY protocol — bulk insert 10-50x faster than INSERT
• LISTEN/NOTIFY — first-class realtime notifications

Usage

[dependencies]
sentinel-driver = "0.1"

use sentinel_driver::{Config, Connection};

#[tokio::main]
async fn main() -> Result<(), sentinel_driver::Error> {
    let config = Config::builder()
        .host("localhost")
        .database("mydb")
        .user("postgres")
        .password("secret")
        .build()?;

    let mut conn = Connection::connect(&config).await?;
    let rows = conn.query("SELECT id, name FROM users", &[]).await?;

    for row in &rows {
        let id: i32 = row.get(0)?;
        let name: &str = row.get(1)?;
        println!("{}: {}", id, name);
    }

    Ok(())
}
