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>
pub fn from_le_bytes(bytes: T::Repr) -> CtOption<Self>
Decode from little endian bytes.
source§impl NonZero<Limb>
impl NonZero<Limb>
sourcepub const fn new_unwrap(n: Limb) -> Self
