Methods

impl DataColumn

fn empty() -> DataColumn

Constructs an empty data column.

fn push(&mut self, val: &str)

Pushes a new &str to the column.

fn shrink_to_fit(&mut self)

Shrink the column to fit the data.

fn into_vec<T: FromStr>(self) -> Result<Vec<T>, DataError>

Consumes self and returns a Vec of the requested type.

Failures

• DataCastError : Returned when the data cannot be parsed to the requested type.

fn cast<T: FromStr>(&self) -> Option<Vec<T>>

Cast the data to the requested type.

Returns a Vec of the requested type wrapped in an option.

fn into_iter_cast<U: FromStr>(self) -> Map<IntoIter<String>, fn(String) -> Result<U, U::Err>> where U: FromStr

Consumes self and returns an iterator which parses the data to the specified type returning results.

The iterator will return a result on next() detailing the outcome of the parse.
