pub trait RoundFrom<T> {
fn round_from(x: T) -> Self;
}
Expand description
A trait for types that can be converted with precision loss.
This is our own implementation of a “lossy From” trait. It is essentially adapted from https://github.com/rust-lang/rfcs/pull/2484.
If and when such a trait is standardized, we should switch to that. Alternatively, a case can be made it should move somewhere else, or we should adopt a similar trait (it has some similarity to AsPrimitive from num_traits).
Required Methods§
fn round_from(x: T) -> Self
fn round_from(x: T) -> Self
Performs the conversion.
