Implementations§
Source§impl<T> NonZero<T>
impl<T> NonZero<T>
Sourcepub fn from_be_bytes(bytes: T::Repr) -> CtOption<Self>
pub fn from_be_bytes(bytes: T::Repr) -> CtOption<Self>
Decode from big endian bytes.
Sourcepub fn from_le_bytes(bytes: T::Repr) -> CtOption<Self>

impl NonZero<Limb>
Sourcepub const fn new_unwrap(n: Limb) -> Self

from a NonZeroU32
(const-friendly)
Sourcepub const fn from_u64(n: NonZeroU64) -> Self
pub const fn from_u64(n: NonZeroU64) -> Self
Create a NonZero<Uint>
from a NonZeroU64

Layout§
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
