Struct measurements::angle::Angle
[−]
[src]
pub struct Angle { /* fields omitted */ }
The 'Angle' struct can be used to deal with angles in a common way.
Example
use measurements::Angle; let whole_cake = Angle::from_degrees(360.0); let pieces = 6.0; let slice = whole_cake / pieces; println!("Each slice will be {} degrees", slice.as_degrees());
