AppendState

Struct AppendState 

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

动态 Append 状态 — 对齐 PHP $this->append 实例属性

PHP 中 $append 是实例属性,可通过 append() 方法动态修改:

  • append($fields) 默认覆盖(Conversion.php 第 90-94 行)
  • append($fields, true) 合并(Conversion.php 第 91-93 行)

Rust 中通过 AppendState 持有动态状态,None 表示使用静态 BaseModel::append()

§鲜视达项目实际用法

项目内 12 个模型使用静态 $append 声明,零动态 ->append() 调用。 此结构提供框架能力补全,业务模型按需使用。

Implementations§

Source§

impl AppendState

Source

pub fn new() -> Self

创建空状态(使用静态默认)

Source

pub fn replace(&mut self, fields: Vec<String>)

覆盖动态 append(对齐 PHP $model->append($fields) 默认行为)

Source

pub fn merge(&mut self, fields: Vec<String>)

合并到动态 append(对齐 PHP $model->append($fields, true)

Source

pub fn dynamic_fields(&self) -> Option<&Vec<String>>

获取动态 append 字段(如果有)
