Struct DbNexusAdapter 

Source
pub struct DbNexusAdapter { /* private fields */ }
Expand description

dbnexus 适配器

将 dbnexus 库的 DbPool 适配为 Database trait。 使用 Sea-ORM 进行批量插入操作。

§功能要求

  • 需要启用 dbnexus feature
  • 支持 PostgreSQL、MySQL、SQLite、DuckDB 数据库

§示例

use inklog::infrastructure::database::{Database, DbNexusAdapter};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let db = DbNexusAdapter::new("postgres://user:pass@localhost/logs", 10).await?;
     
    let healthy = db.is_healthy().await;
    println!("Database healthy: {}", healthy);
     
    Ok(())
}

Implementations§

Source§

impl DbNexusAdapter

Source

pub async fn new(url: &str, pool_size: u32) -> Result<Self, InklogError>

创建新的 dbnexus 适配器

§参数
  • url - 数据库连接字符串
  • pool_size - 连接池大小(最大连接数)
§返回

成功返回 Ok(Self),失败返回 Err(InklogError)

§错误
  • InklogError::DatabaseError - 连接池创建失败
§示例
// PostgreSQL
let db = DbNexusAdapter::new("postgres://user:pass@localhost/logs", 10).await?;

// MySQL
let db = DbNexusAdapter::new("mysql://user:pass@localhost/logs", 10).await?;

// SQLite
let db = DbNexusAdapter::new("sqlite://logs.db", 1).await?;
Source

pub async fn with_table_name( url: &str, pool_size: u32, table_name: &str, ) -> Result<Self, InklogError>

  • table_name - 日志表名称
Source

pub async fn with_full_config( url: &str, pool_size: u32, table_name: &str, permissions_path: Option<String>, admin_role: &str, ) -> Result<Self, InklogError>

创建带完整配置的适配器

支持自定义权限配置文件路径和管理员角色名。 构造完成后自动调用 ensure_table_exists() 创建日志表。

§参数
  • url - 数据库连接字符串
  • pool_size - 连接池大小(最大连接数)
  • table_name - 日志表名称
  • permissions_path - 权限配置文件路径,None 时不启用权限校验

Source

pub fn from_pool(pool: DbPool, table_name: &str) -> Result<Self, InklogError>

从现有 DbPool 创建适配器

用于需要共享连接池的场景。

§参数
  • pool - 已创建的连接池实例
  • table_name - 日志表名称
Source

pub fn from_connection_pool( pool: Arc<dyn ConnectionPool + Send + Sync>, table_name: &str, ) -> Result<Self, InklogError>

从已有的 ConnectionPool trait 对象创建适配器

用于 trait-kit DI 场景:kit 提供 Arc<dyn ConnectionPool + Send + Sync>, 直接包装为 Database trait 实现,无需重新创建连接池。

§参数
  • pool - dbnexus 连接池 trait 对象(通常来自 kit.require::<DbNexusModule>()
  • table_name - 日志表名称
Source

pub fn pool(&self) -> &dyn ConnectionPool

获取底层连接池引用

Source

pub fn pool_arc(&self) -> Arc<dyn ConnectionPool + Send + Sync>

获取底层连接池的 Arc 克隆

用于需要共享连接池创建新适配器的场景(见 Self::from_connection_pool)。

Source

pub fn table_name(&self) -> &str

获取表名
