impl<T: NumCast + Copy, U> Point3D<T, U>

Source

pub fn cast<NewT: NumCast>(self) -> Point3D<NewT, U>

Cast from one numeric representation to another, preserving the units.

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

Source

pub fn try_cast<NewT: NumCast>(self) -> Option<Point3D<NewT, U>>

Fallible cast from one numeric representation to another, preserving the units.

When casting from floating point to integer coordinates, the decimals are truncated as one would expect from a simple cast, but this behavior does not always make sense geometrically. Consider using round(), ceil() or floor() before casting.

Source

Source

pub fn to_usize(self) -> Point3D<usize, U>

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

Source

pub fn to_u32(self) -> Point3D<u32, U>

Cast into an u32 point, truncating decimals if any.

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

When casting from floating point points, it is worth considering whether to round(), ceil() or floor() before the cast in order to obtain the desired conversion behavior.

Source

pub fn to_i64(self) -> Point3D<i64, U>

Cast into an i64 point, truncating decimals if any.
