• Allows to overwrite the field content via Self::write

pub fn read(&mut self) -> Result<FieldValue, Error>

Reads and returns the value

pub fn read_as<ValueType>(&mut self) -> Result<ValueType, Error>

where ValueType: TryFrom<FieldValue, Error = FieldConversionError>,

impl<'a, T> FieldRef<'a, T>

where T: Seek + Write,

pub fn write<ValueType>(&mut self, value: &ValueType) -> Result<(), Error>

where ValueType: WritableAsDbaseField,

Writes the value
