Trait num_traits::cast::NumCast[−][src]

pub trait NumCast: Sized + ToPrimitive {
    fn from<T: ToPrimitive>(n: T) -> Option<Self>;
}
Expand description

An interface for casting between machine scalars.

Required methods

fn from<T: ToPrimitive>(n: T) -> Option<Self>[src]

Creates a number from another value that can be converted into a primitive via the ToPrimitive trait.
