std::num::NonZeroI16 - Rust
Description: API documentation for the Rust `NonZeroI16` struct in crate `std`.
Keywords: rust, rustlang, rust-lang, NonZeroI16

# 1.34.0[−][src]Struct std::num::NonZeroI16

    #[repr(transparent)]
    pub struct NonZeroI16(_);

An integer that is known not to equal zero.

This enables some memory layout optimization. For example, `Option<NonZeroI16>` is the same size as `i16`:

    use std::mem::size_of;
    assert_eq!(size_of::<Option<core::num::NonZeroI16>>(), size_of::<i16>());

Run

## Methods

### `impl NonZeroI16`[src]

#### `pub const unsafe fn new_unchecked(n: i16) -> NonZeroI16`[src]

# Safety

The value must not be zero.

#### `pub fn new(n: i16) -> Option<NonZeroI16>`[src]

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

#### `pub const fn get(self) -> i16`[src]

Returns the value as a primitive type.
