Crate any_null 

AnyNull

A simple Rust utility crate for unifying various “kinds” of null. Instead of ptr::null(), ptr::null_mut(), None::<&_>, etc., now all forms of null can be called just null().

Traits

NoneIsNull

Many types are not themselves nullable, but when wrapped in an Option effectively use None as null (especially with the niche-filling optimization).

Nullable

Any type that can be some form of null.

Functions

is_null

Wraps around <P as Nullable>::is_null(ptr)

null

Conveniently wraps arounnd <P as Nullable>::NULL.
