Enum DocValue 

#[non_exhaustive]
pub enum DocValue {
    String(String),
    Bool(bool),
    Int(i64),
    Float(f64),
    DateTime(DateTime<Utc>),
    Date(NaiveDate),
    NaiveDateTime(NaiveDateTime),
    Empty,
    RichText(Vec<RichRun>),
    Image(ImageData),
}

通用文档值 – Rust 类型与 DOCX 内容之间的桥梁。

每个 DocConverter 都从此枚举读取或写入，正如 CellValue 在 Rust 类型与 Excel 单元格数据之间充当中介。

对应 Java: com.alibaba.excel.metadata.data.CellValue / ReadCellData / WriteCellData

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

String(String)

纯文本字符串。

Bool(bool)

布尔值。

Int(i64)

64 位有符号整数。

Float(f64)

64 位浮点数。

DateTime(DateTime<Utc>)

UTC 日期时间。

Date(NaiveDate)

仅日期（无时间分量）。

NaiveDateTime(NaiveDateTime)

无时区的日期时间。

Empty

空值 / null。

RichText(Vec<RichRun>)

富文本（格式化文本片段）。

Image(ImageData)

图片数据（原始字节 + 元数据）。
