Enum Value 

#[non_exhaustive]
pub enum Value {
    Empty,
    Text(String),
    Number(f64),
    Bool(bool),
    Date(Date),
}

A cell value.

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.

Empty

No value; shown as an empty cell.

Text(String)

A string.

Number(f64)

A number.

Bool(bool)

A yes/no value.

Date(Date)

A calendar date.

Implementations
