Trait Mean

source 
pub trait Mean<'a, D>: Sum<&'a Self> + Div<Output = D>
where
    Self: 'a,
{
    // Required method
    fn from_usize(n: usize) -> Self;
}
Expand description

Helper-trait for types used by mean.

This is implemented generically when the feature generic-impl is enabled.

Required Methods§

source

fn from_usize(n: usize) -> 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.

Implementors§

source§

impl<'a, T> Mean<'a, <T as Div>::Output> for T
where T: 'a + Sum<&'a Self> + Div + FromPrimitive,

Available on crate feature generic-impls only.
