# 1.28.0[−][src]Struct std::num::NonZeroU16

    #[repr(transparent)]
    pub struct NonZeroU16(_);

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, `Option<NonZeroU16>` is the same size as `u16`:

    use std::mem::size_of;
    assert_eq!(size_of::<Option<std::num::NonZeroU16>>(), size_of::<u16>());Run

## Methods

###

`impl NonZeroU16` | [src]

####

# Safety

The value must not be zero.

Create a non-zero if the given value is not zero.

####

`pub const fn get(self) -> u16` | [src]

## 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`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
