Struct BehaviorRegistry 

pub struct BehaviorRegistry { /* private fields */ }

Behavior 注册中心 — 管理多个 Behavior 的注册与分发

线程安全：内部使用 RwLock，可在多线程环境下共享。

示例

use sz_orm_model::behaviors::{BehaviorRegistry, TimestampBehavior, BlameableBehavior, Behavior};
use sz_orm_model::hooks::HookContext;
use sz_orm_model::Value;
use std::collections::HashMap;

let mut registry = BehaviorRegistry::new();
registry.register(Box::new(TimestampBehavior::default_fields()));
registry.register(Box::new(BlameableBehavior::default_fields()));

let ctx = HookContext::default().with_operator(100).with_timestamp(1700000000);
let mut attrs = HashMap::new();
registry.before_insert(&ctx, &mut attrs).unwrap();
assert_eq!(attrs.get("created_at"), Some(&Value::I64(1700000000)));
assert_eq!(attrs.get("created_by"), Some(&Value::I64(100)));

Implementations

impl BehaviorRegistry

pub fn new() -> BehaviorRegistry
