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
• Cancel query -- CancelToken for safe query cancellation
• Per-query timeout -- auto-cancel with configurable statement_timeout
• Array types -- Vec<T> encode/decode for PostgreSQL arrays

Usage

[dependencies]
sentinel-driver = "0.1"

use sentinel_driver::{Config, Connection};

#[tokio::main]
async fn main() -> Result<(), sentinel_driver::Error> {
    let config = Config::parse("postgres://user:pass@localhost/mydb")?;
    let mut conn = Connection::connect(config).await?;

    let rows = conn.query("SELECT id, name FROM users WHERE id = $1", &[&42i32]).await?;
    for row in &rows {
        let id: i32 = row.get(0);
        let name: String = row.get(1);
    }

    Ok(())
}
