Type Alias NonExtremeU8

pub type NonExtremeU8 = NonValueU8<{ u8::MAX }>;

An unsigned integer that is known not to equal its most extreme value (MAX).

Unlike the NonValue* types in general, this type alias implements the Default and ConstDefault traits.

Aliased Type

struct NonExtremeU8(/* private fields */);

Implementations

impl<const V: u8> NonValueU8<V>

pub const MAX: Self

Returns the maximum possible value.

pub const MIN: Self

Returns the minimum possible value.

pub const VALID_VALUES: u8 = 255u8

Returns the number of valid values.

pub const INVALID_VALUES: u8 = 1u8

Returns the number of invalid values.

pub const fn new(value: u8) -> Option<Self>

Returns a NonValueU8 with the given value, if it is not equal to V.

pub const unsafe fn new_unchecked(value: u8) -> Self

Returns a NonValueU8 if the given value if it is not equal to V.

Panics

Panics in debug if the given value is equal to V.

Safety

The given value must never be equal to V.

pub const fn get(&self) -> u8

Returns the value as a primitive type.

pub const fn is_max(&self) -> bool

Returns true if it is equal to the maximum value (MAX).

pub const fn is_min(&self) -> bool

Returns true if it is equal to the minimum value (MIN).

pub const fn checked_add(&self, other: u8) -> NumResult<Self>

Checked integer addition. Computes self + rhs.

Errors

Returns Overflow if the operations overflows, or Invalid if the result equals the forbidden value V.

pub const fn checked_sub(&self, other: u8) -> NumResult<Self>

Checked integer substration. Computes self - rhs.

Errors

Returns Overflow if the operations overflows, or Invalid if the result equals the forbidden value V.

pub const fn strict_add(&self, other: u8) -> Self

Strict integer addition. Computes self + rhs.

Panics

Panics on overflow or if the result equals the forbidden value V.

pub const fn strict_sub(&self, other: u8) -> Self

Strict integer substration. Computes self - rhs.

Panics

Panics on overflow or if the result equals the forbidden value V.

pub const fn saturating_add(&self, other: u8) -> Self

Saturating integer addition. Computes self + rhs.

Saturates at the numeric bounds instead of overflowing. If the result would equal V it will return V - 1.

pub const fn saturating_sub(&self, other: u8) -> Self

Saturating integer substration. Computes self - rhs.

Saturates at the numeric bounds instead of overflowing. If the result would equal V it will return V + 1.

pub const fn wrapping_add(&self, other: u8) -> Self

Wraping integer addition. Computes self + rhs.

Wraps at the numeric bounds instead of overflowing. If the result would equal V it will return V + 1.

pub const fn wrapping_sub(&self, other: u8) -> Self

Wraping integer subtraction. Computes self - rhs.

Wraps at the numeric bounds instead of overflowing. If the result would equal V it will return V - 1.
