pub trait NumCast: Sized + ToPrimitive {
// Required method
fn from<T: ToPrimitive>(n: T) -> Option<Self>;
}
Expand description
An interface for casting between machine scalars.
Required Methods§
Sourcefn from<T: ToPrimitive>(n: T) -> Option<Self>
fn from<T: ToPrimitive>(n: T) -> Option<Self>
Creates a number from another value that can be converted into
a primitive via the ToPrimitive
trait. If the source value cannot be
represented by the target type, then None
is returned.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
