Struct zerovec::ule::NichedOption
source · #[non_exhaustive]#[repr(transparent)]pub struct NichedOption<U, const N: usize>(pub Option<U>);
Expand description
Optional type which uses NichedOptionULE<U,N>
as ULE type.
The implementors guarantee that N == core::mem::sizeo_of::<Self>()
[repr(transparent)
] guarantees that the layout is same as Option<U>
Tuple Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.0: Option<U>
