Enum ErrorCode 

#[repr(u32)]
pub enum ErrorCode {
    InvalidArgument = 1,
    Failed = 2,
    Storage = 3,
    Busy = 6,
}

EngineError 的稳定数字码，供宿主和 C ABI 按数字分支，不必解析说明文字。编号与引擎库 C ABI 草案的返回码共用一个空间：0 是成功，4（不支持）、5（revision 不符）、7（会话已毒化）、8（空指针）留给 C ABI 自己的情形，引擎不产生它们。已发布的编号只追加、不改、不复用。

Variants

InvalidArgument = 1

Failed = 2

Storage = 3

SQLite 或文件系统出错（EngineError::Sqlite、EngineError::Io）。

Busy = 6
