Required Associated Types§

type Scalar<'a>: MinMax where Self: 'a

Required Methods§

fn min_ignore_nan_kernel(&self) -> Option<Self::Scalar<'_>>

fn max_ignore_nan_kernel(&self) -> Option<Self::Scalar<'_>>

fn min_propagate_nan_kernel(&self) -> Option<Self::Scalar<'_>>

fn max_propagate_nan_kernel(&self) -> Option<Self::Scalar<'_>>

Provided Methods§

fn min_max_ignore_nan_kernel( &self, ) -> Option<(Self::Scalar<'_>, Self::Scalar<'_>)>

fn min_max_propagate_nan_kernel( &self, ) -> Option<(Self::Scalar<'_>, Self::Scalar<'_>)>

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.
