CacheValue

Enum CacheValue 

Source
pub enum CacheValue {
    Number(String),
    Json(String),
}
Expand description

缓存值(区分 is_numeric 短路与 JSON 序列化)

对齐 PHP think\cache\Driver::serialize/unserialize 行为:

  • Number(s):对齐 is_numeric($data) === true,存储为字符串
  • Json(s):对齐 serialize($data),存储为 JSON 字符串

PHP bug 复刻unserializeis_numeric 返回 string,而非 int。 本枚举通过 Number(String) 携带原始字符串,反序列化时直接返回 string, 不还原为 int 类型。

Variants§

§

Number(String)

数值型缓存值(对齐 PHP is_numeric 短路)

存储为字符串形式,反序列化时直接返回 string。

§

Json(String)

JSON 序列化缓存值(对齐 PHP serialize

存储为 JSON 字符串,反序列化时通过 serde_json::from_str 还原。

Implementations§

Source§

impl CacheValue

Source

pub fn to_bytes(&self) -> Vec<u8>

序列化缓存值为存储字节

对齐 PHP Driver::serialize($data):返回字符串后转字节。

Source

pub fn from_bytes(bytes: &[u8]) -> Result<CacheValue, CacheError>

从存储字节反序列化缓存值

对齐 PHP Driver::unserialize($data)

  • is_numeric → 返回 Number(s)(保留原始字符串)
  • 否则 → 返回 Json(s)
Source

pub fn is_number(&self) -> bool

是否为数值型(对齐 PHP is_numeric
