随意的处理数据

数据处理模型

optional_model

  • value
  • processor
  • validator
  • align
设计思路
  • value和type存储数据类型和值，附加函数处理数据类型转换。
  • processor处理数据
  • validator验证数据
  • align反射赋值到指定字段
扩展功能
  • 类型与值： 添加多个数据来源接口，添加json序列化实现，添加国际化错误返回接口
  • 处理器： 完善更多的处理器函数，添加自定义处理器接口，优化处理器执行
  • 验证器：完善更多的验证起函数，添加自定义验证起接口，优化验证逻辑
  • 赋值： 完善反射赋值，添加多种赋值方式。

type Type 

type Type struct {
	// contains filtered or unexported fields
}

Type represents value types within the type system.

This is a closed interface type, meaning that only the concrete implementations provided within this package are considered valid.

func MapStringValEmpty 

func MapStringValEmpty() Value

func NullVal 

func NullVal(t Type) Value

NullVal returns a null value of the given type. A null can be created of any type, but operations on such values will always panic. Calling applications are encouraged to use nulls only sparingly, particularly when user-provided expressions are to be evaluated, since the precence of nulls creates a much higher chance of evaluation errors that can't be caught by a type checker.

func ParseFloat64Val 

func ParseFloat64Val(s string) (Value, error)

ParseNumberVal returns a Value of type number produced by parsing the given string as a decimal real number. To ensure that two identical strings will always produce an equal number, always use this function to derive a number from a string; it will ensure that the precision and rounding mode for the internal big decimal is configured in a consistent way.

If the given string cannot be parsed as a number, the returned error has the message "a number is required", making it suitable to return to an end-user to signal a type conversion error.

If the given string contains a number that becomes a recurring fraction when expressed in binary then it will be truncated to have a 512-bit mantissa. Note that this is a higher precision than that of a float64, so coverting the same decimal number first to float64 and then calling NumberFloatVal will not produce an equal result; the conversion first to float64 will round the mantissa to fewer than 512 bits.

func StringVal 

func StringVal(v string) Value

StringVal returns a Value of type String whose internal value is the given string.

Strings must be UTF-8 encoded sequences of valid unicode codepoints, and they are NFC-normalized on entry into the world of cty values.

If the given string is not valid UTF-8 then behavior of string operations is undefined.

func Uint16Val 

func Uint16Val(v uint16) Value

func Uint32Val
