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
dbnexusfeature - 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(())

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

成功返回 Ok(Self),失败返回 Err(InklogError)
§错误
InklogError::DatabaseError- 连接池创建失败

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admin_role- 管理员角色名
Sourcepub fn from_connection_pool(
pool: Arc<dyn ConnectionPool + Send + Sync>,
table_name: &str,
) -> Result<Self, InklogError>
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
Sourcepub fn pool(&self) -> &dyn ConnectionPool
pub fn pool(&self) -> &dyn ConnectionPool
获取底层连接池引用
Sourcepub fn pool_arc(&self) -> Arc<dyn ConnectionPool + Send + Sync> ⓘ
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)。
Sourcepub fn table_name(&self) -> &str
pub fn table_name(&self) -> &str
获取表名
