Floating point numbers

This trait bound multiplexes to the most common assumption of floating point number and implement them for 32bit and 64bit floating points. They are used in records of a dataset and, for regression task, in the targets as well.

Required Associated Types

type Lapack: Float

Provided Methods

fn cast<T: NumCast>(x: T) -> Self

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.
