Enum Boundaries

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

Iterator for reading color data.

Casting is the same as Numbers.

Variants

F32(GenericBoundaries<f32, R>)

F64(GenericBoundaries<f64, R>)

I64(GenericBoundaries<i64, R>)

Date(GenericBoundaries<NaiveDate, R>)

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

Implementations

impl<R: ReadAt> Boundaries<R>

pub fn try_into_f64(self) -> Result<BoundariesF64<R>, Error>

Turns this into an f64 boundary 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<BoundariesI64<R>, Error>

Turns this into an i64 boundary 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.
