Trait IsUnit Copy item path Source pub trait IsUnit {
// Required method
fn is_unit (&self) -> bool ;
}Expand description Determines whether a number is a unit of its ring, meaning that it has a multiplicative inverse
in the same ring.
The Gaussian integers have four units, $\pm 1$ and $\pm i$; in a field every nonzero element is
a unit. No type in this crate implements this trait; it exists for complex types downstream,
like Gaussian integers.
This trait is dyn compatible .
In older versions of Rust, dyn compatibility was called "object safety".
Determines whether a number is a unit: whether it is finite and nonzero, so that it
has a multiplicative inverse. NaN and the infinities are not units.
