# Trait std::num::Zero [−] [src]

    pub trait Zero {
        fn zero() -> Self;
    }

Unstable (`zero_one` #27739)

: unsure of placement, wants to use associated constants

Types that have a "zero" value.

This trait is intended for use in conjunction with `Add`, as an identity: `x + T::zero() == x`.

## Required Methods

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
