Expand description

数据库配置结构体

用于配置数据库连接池的各项参数,包括连接 URL、连接数限制、超时设置等。 所有字段都提供了默认值,可以只设置必要的参数。

§示例

use baichun_framework_db::DatabaseConfig;

let config = DatabaseConfig {
    url: "mysql://user:pass@localhost/db_name".to_string(),
    max_connections: 20,
    min_connections: 5,
    ..Default::default()
};

Fields§

§url: String

数据库连接 URL

支持以下格式:

  • MySQL: mysql://user:pass@host:port/dbname
  • PostgreSQL: postgresql://user:pass@host:port/dbname
  • SQLite: sqlite:///path/to/db.sqlite
§max_connections: u32

连接池中的最大连接数

默认值为 CPU 核心数的 2 倍

§min_connections: u32

连接池中的最小连接数

默认值为 CPU 核心数,最小为 1

§connect_timeout: u64

连接超时时间(秒)

建立新连接时的超时时间,默认为 10 秒

§max_lifetime: u64

连接最大生命周期(秒)

一个连接在连接池中的最长存活时间,默认为 1 小时

§idle_timeout: u64

空闲连接超时时间(秒)

空闲连接在被关闭前的最长等待时间,默认为 10 分钟

§acquire_timeout: u64

获取连接超时时间(秒)

从连接池获取连接的最长等待时间,默认为 30 秒
