Trait SoftDelete 

pub trait SoftDelete: Model {
    // Required methods
    fn soft_delete_field() -> &'static str;
    fn is_deleted(&self) -> bool;
}

软删除 trait

实现此 trait 的 Model 在调用 delete 时，实际执行 UPDATE SET {field} = NOW() WHERE pk = ? 而非 DELETE。

Required Methods

fn soft_delete_field() -> &'static str

软删除字段名（如 deleted_at）

fn is_deleted(&self) -> bool

是否已软删除（由 Model 数据行判断）

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
