Struct std::num::NonZeroI8 [] [src]

pub struct NonZeroI8(_);
Deprecated since 1.26.0

: signed non-zero integers are considered for removal due to lack of known use cases. If you’re using them, please comment on https://github.com/rust-lang/rust/issues/49137

🔬 This is a nightly-only experimental API. (nonzero #49137)

An integer that is known not to equal zero.

This may enable some memory layout optimization such as:

use std::mem::size_of;
assert_eq!(size_of::<Option<std::num::NonZeroU32>>(), size_of::<u32>());Run

Methods

impl NonZeroI8
[src]

🔬 This is a nightly-only experimental API. (nonzero #49137)
