Struct std::num::NonZeroI32
[−]
[src]
pub struct NonZeroI32(_);
: 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
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
