Struct AccessorRegistry 

pub struct AccessorRegistry { /* private fields */ }

Accessor / Mutator / Cast 注册中心

管理字段级别的读取器、设置器、类型转换器。

Implementations

impl AccessorRegistry

pub fn new() -> AccessorRegistry

创建空注册中心

pub fn register_accessor(&mut self, accessor: Box<dyn Accessor>)

注册 Accessor

pub fn register_mutator(&mut self, mutator: Box<dyn Mutator>)

注册 Mutator

pub fn register_cast(&mut self, field: impl Into<String>, cast: CastType)

注册类型转换

pub fn read(&self, field: &str, value: Value) -> Value

应用读取流程：cast_read → accessor.read

pub fn write(&self, field: &str, value: Value) -> Value

应用写入流程：mutator.write → cast_write

pub fn cast_read(&self, field: &str, value: Value) -> Value

仅应用类型转换（读取方向）

pub fn cast_write(&self, field: &str, value: Value) -> Value

仅应用类型转换（写入方向）

pub fn has_accessor(&self, field: &str) -> bool

检查字段是否已注册 Accessor

pub fn has_mutator(&self, field: &str) -> bool

检查字段是否已注册 Mutator

pub fn has_cast(&self, field: &str) -> bool

检查字段是否已注册 Cast

pub fn get_cast(&self, field: &str) -> Option<CastType>

获取字段已注册的 CastType

pub fn accessor_count(&self) -> usize

已注册 Accessor 数量

pub fn mutator_count(&self) -> usize

已注册 Mutator 数量

pub fn cast_count(&self) -> usize

已注册 Cast 数量

Trait Implementations

impl Default for AccessorRegistry

fn default() -> AccessorRegistry

Returns the “default value” for a type.
