Variants

Character(Option<String>)

dBase String type

A string full of ‘pad bytes’ is considered None

Tuple Fields of Character

0: Option<String>

Numeric(Option<f64>)

dBase type to represent numbers, stored as String in the file

Tuple Fields of Numeric

0: Option<f64>

Logical(Option<bool>)

dBase type for boolean values, stored as a character in the file

Tuple Fields of Logical

0: Option<bool>

Date(Option<Date>)

dBase type for dates, stored as a string in the file

Tuple Fields of Date

0: Option<Date>

Float(Option<f32>)

Another dBase type to represent numbers, stored as String in the file
