Source
pub struct DataSourcePoolConfig {
    pub url: String,
    pub max_connections: u32,

Expand description

业务作用:承载两种数据库连接池共同使用的启动配置,不解释具体 URL scheme。

Fields§

§url: String

数据库连接串;driver 包装层负责校验 scheme。

§max_connections: u32

连接池上限。

§min_connections: u32

连接池下限。

§acquire_timeout_ms: u64

从池中获取连接的等待上限,毫秒。

§connect_timeout_ms: u64

建立单条连接的等待上限,毫秒。

§probe_on_start: bool

启动时是否先执行真实单连接探测。

Implementations§

Source§

impl DataSourcePoolConfig

Source

pub fn validate_common(&self) -> Result<(), PoolConfigError>

业务作用:校验与 driver 无关的池容量和超时合同。

参数说明: 无。

返回:公共配置可用于建池时返回 Ok;失败时不产生连接副作用。

Source

pub fn endpoint(&self) -> String

业务作用:返回可安全写入日志的 host、端口与 database 定位信息。

参数说明: 无。

返回:移除 scheme、userinfo、query 与 fragment 后的 endpoint;无法识别时返回固定占位符。
