Struct BoundedIsize 

pub struct BoundedIsize<const MIN: isize, const MAX: isize> { /* private fields */ }

Bounded type (inclusive) that holds a value that is MIN <= value <= MAX

Has the same representation as the primitive type.

Safety

Creating an instance with MIN > MAX is undefined behavior.

Implementations

impl<const MIN: isize, const MAX: isize> BoundedIsize<MIN, MAX>

pub const MAX: isize = MAX

Upper bound.

pub const MAX_PACKED: Self

Upper bound, represented as the bounded type.

pub const MIN: isize = MIN

Lower bound.

pub const MIN_PACKED: Self

Lower bound, represented as the bounded type.

pub const fn min(&self) -> isize

Returns Self::MIN.

pub const fn max(&self) -> isize

Returns Self::MAX.

pub fn new<N: Into<isize> + PartialOrd<isize> + Ord>( value: N, ) -> Result<Self, Error>

Create a new value of the type.

Returns the error if the provided value was outside of the defined bounds.

pub unsafe fn new_unchecked<N: Into<isize>>(value: N) -> Self

Create a new value of the type without any checks.

Safety

User is responsible for providing the value that is already between the defined bounds. Creating a value outside of the defined bounds is undefined behavior.

pub fn new_clamped<N: Into<isize> + PartialOrd<isize> + Ord>(value: N) -> Self

Create a new value of the type.

If value is within range, returns a new instance; otherwise, clamps it to the upper or lower bound.

pub fn get(self) -> isize

Returns the underlying value.

This value is guaranteed to be between Self::MIN and Self::MAX.

pub const fn get_const(&self) -> isize

const-compatible Self::get.

pub fn is_in_bounds(n: &isize) -> bool

Check if abstract value is within bounds.

pub fn clamp(n: isize) -> isize

Clamp the provided n between the Self::MIN and Self::MAX.

pub fn checked_add<Rhs: Into<isize>>(self, rhs: Rhs) -> Option<Self>

Checked integer addition. Computes self + rhs, returning None if either bound overflow or integer overflow occurred.

pub unsafe fn unchecked_add<Rhs: Into<isize>>(self, rhs: Rhs) -> Self

Unchecked integer addition. Computes self + rhs, assuming overflow cannot occur.

Safety

This results in undefined behavior if the result overflows the primitive type’s bounds or the [MIN, MAX] bounds of this type.

pub fn checked_sub<Rhs: Into<isize>>(self, rhs: Rhs) -> Option<Self>

Checked integer subtraction. Computes self - rhs, returning None if either bound overflow or integer overflow occurred.

pub unsafe fn unchecked_sub<Rhs: Into<isize>>(self, rhs: Rhs) -> Self

Unchecked integer subtraction. Computes self - rhs, assuming overflow cannot occur.

Safety

This results in undefined behavior if the result overflows the primitive type’s bounds or the [MIN, MAX] bounds of this type.

pub fn checked_mul<Rhs: Into<isize>>(self, rhs: Rhs) -> Option<Self>

Checked integer multiplication. Computes self * rhs, returning None if either bound overflow or integer overflow occurred.

pub unsafe fn unchecked_mul<Rhs: Into<isize>>(self, rhs: Rhs) -> Self

Unchecked integer multiplication. Computes self * rhs, assuming overflow cannot occur.

Safety

This results in undefined behavior if the result overflows the primitive type’s bounds or the [MIN, MAX] bounds of this type.

pub fn checked_div<Rhs: Into<isize>>(self, rhs: Rhs) -> Option<Self>

Checked integer division. Computes self / rhs, returning None if either bound overflow or integer overflow occurred.

pub fn checked_rem<Rhs: Into<isize>>(self, rhs: Rhs) -> Option<Self>

Checked integer remainder. Computes self % rhs, returning None if either bound overflow or integer overflow occurred.

pub fn checked_neg(self) -> Option<Self>

Checked negation. Computes -self, returning None if bound overflow or self == inner_num_repr::MIN occurred.

pub fn checked_pow(self, exp: u32) -> Option<Self>

Checked integer exponentiation. Computes self.pow(), returning None if bound overflow or self == inner_num_repr::MIN occurred.
