Trait Niche 

Source 
pub trait Niche {
    type NeedsTag: Bit;
    type N: ArrayLength;
    type Next;

    // Required method

}
Expand description

True or fake (placeholder) niche.

Required Associated Types§

Source

type NeedsTag: Bit

Whether this is a fake niche (true niches, i.e. those which don’t need a tag, don’t represent a value).

Source

type N: ArrayLength

Length in bytes.

Source

type Next

What we’re left with once we occupy Self::niche.

Required Methods§

Source

fn niche() -> GenericArray<u8, Self::N>

Get the niche bytes.

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.
