Enum where each variant stores the record value

Variants

Character(Option<String>)

dBase String type

A string full of ‘pad bytes’ is considered None

Numeric(Option<f64>)

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

Logical(Option<bool>)

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

Date(Option<Date>)

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

Float(Option<f32>)

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

Integer(i32)

Currency(f64)

DateTime(DateTime)

Double(f64)

Memo(String)

Memo is a dBase type that allows to store Strings that are longer than 255 bytes. These strings are stored in an external file called the Memo file

Implementations

impl FieldValue

pub fn field_type(&self) -> FieldType

Returns the corresponding field type of the contained value

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FieldValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Date> for FieldValue

fn from(v: Date) -> Self

Converts to this type from the input type.

impl From<DateTime> for FieldValue

fn from(v: DateTime) -> Self

Converts to this type from the input type.
