О чём код?
//! A synchronous client for the PostgreSQL database. //! //! # Example //! //! ```no_run //! use postgres::{Client, NoTls}; //! //! # fn main() -> Result<(), postgres::Error> { //! let mut client = Client::connect("host=localhost user=postgres", NoTls)?; //! //! client.batch_execute(" //! CREATE TABLE person ( //! id SERIAL PRIMARY KEY, //! name TEXT NOT NULL, //! data BYTEA //! ) //! ")?; //! //! let name = "Ferris"; //! let data = None::<&[u8]>; //! client.execute( //! "INSERT INTO person (name, data) VALUES ($1, $2)", //! &[&name, &data], //! )?; //! //! for row in client.query("SELECT id, name, data FROM person", &[])? { //! let id: i32 = row.get(0); //! let name: &str = row.get(1); //! let data: Option<&[u8]> = row.get(2); //! //! println!("found person: {} {} {:?}", id, name, data); //! } //! # Ok(()) //! # } //! ``` //! //! # Implementation //! //! This crate is a lightweight wrapper over tokio-postgres. The `postgres::Client` is simply a wrapper around a //! `tokio_postgres::Client` along side a tokio `Runtime`. The client simply blocks on the futures provided by the async //! client. //! //! # SSL/TLS support //! //! TLS support is implemented via external libraries. `Client::connect` and `Config::connect` take a TLS implementation //! as an argument. The `NoTls` type in this crate can be used when TLS is not required. Otherwise, the //! `postgres-openssl` and `postgres-native-tls` crates provide implementations backed by the `openssl` and `native-tls` //! crates, respectively. //! //! # Features //! //! The following features can be enabled from `Cargo.toml`: //! //! | Feature | Description | Extra dependencies | Default | //! | ------- | ----------- | ------------------ | ------- | //! | `with-bit-vec-0_6` | Enable support for the `bit-vec` crate. | [bit-vec](https://crates.io/crates/bit-vec) 0.6 | no | //! | `with-bit-vec-0_7` | Enable support for the `bit-vec` crate. | [bit-vec](https://crates.io/crates/bit-vec) 0.7 | no | //! | `with-bit-vec-0_8` | Enable support for the `bit-vec` crate. | [bit-vec](https://crates.io/crates/bit-vec) 0.8 | no | //! | `with-chrono-0_4` | Enable support for the `chrono` crate. | [chrono](https://crates.io/crates/chrono) 0.4 | no | //! | `with-eui48-0_4` | Enable support for the 0.4 version of the `eui48` crate.
