Enum Numbers

pub enum Numbers<R: ReadAt> {
    F32(GenericNumbers<f32, R>),
    F64(GenericNumbers<f64, R>),
    I64(GenericNumbers<i64, R>),
    Date(GenericNumbers<NaiveDate, R>),
    DateTime(GenericNumbers<DateTime<Utc>, R>),
}

Iterator for reading number data of various types.

You can access the variants directly or use the try_into_f64 and try_into_i64 methods. These methods can both fail so aren’t automatic.

Variants

F32(GenericNumbers<f32, R>)

F64(GenericNumbers<f64, R>)

I64(GenericNumbers<i64, R>)

Date(GenericNumbers<NaiveDate, R>)

DateTime(GenericNumbers<DateTime<Utc>, R>)

Implementations

impl<R: ReadAt> Numbers<R>

pub fn try_into_f64(self) -> Result<NumbersF64<R>, Error>

Turns this into an f64 iterator, casting values.

If the numbers use type i64 this will fail with Error::UnsafeCast. Dates will become days since the ‘1970-01-01’ epoch. Date-times will become seconds since the ‘1970-01-01T00:00:00Z’ epoch with a small loss of precision.

Currently can’t fail but future number types might yield Error::UnsafeCast.

pub fn try_into_i64(self) -> Result<NumbersI64<R>, Error>

Turns this into an i64 iterator, casting values.

Floating-point types will be rejected with Error::UnsafeCast. Dates will become days since the ‘1970-01-01’ epoch. Date-times will become microseconds since the ‘1970-01-01T00:00:00Z’ epoch.
