Struct Size 

pub struct Size {
    pub bits: u16,
    pub refs: u8,
}

A size of a cell.

Fields

bits: u16

Total number of bits in cell slice.

refs: u8

Total number refs in cell slice.

Implementations

impl Size

pub const ZERO: Self

The additive identity for this type, i.e. 0.

pub const BIT: Self

The multiplicative bits identity for this type, i.e. 1 bit.

pub const REF: Self

The multiplicative refs identity for this type, i.e. 1 ref.

pub const MAX: Self

The largest valid value that can be represented by this type.

pub const fn fits_into_cell(&self) -> bool

Returns true if the number of bits and refs is in the valid range for the cell.

pub const fn saturating_add(self, rhs: Self) -> Self

Saturating size addition. Computes self + rhs for bits and refs, saturating at the numeric bounds instead of overflowing.

pub const fn saturating_sub(self, rhs: Self) -> Self

Saturating size substraction. Computes self - rhs for bits and refs, saturating at the numeric bounds instead of overflowing.

pub const fn is_zero(self) -> bool

Returns true if there are no bits and refs.

Trait Implementations

impl Add<Size> for CellTreeStats

type Output = CellTreeStats

The resulting type after applying the + operator.

fn add(self, rhs: Size) -> Self::Output

Performs the + operation.

impl Add for Size

type Output = Size

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl AddAssign<Size> for CellTreeStats

fn add_assign(&mut self, rhs: Size)

Performs the += operation.

impl AddAssign for Size

fn add_assign(&mut self, rhs: Self)

Performs the += operation.

impl Clone for Size

fn clone(&self) -> Size

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Size

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Size

fn default() -> Size

Returns the “default value” for a type.

impl From<Size> for CellTreeStats

fn from(value: Size) -> Self

Converts to this type from the input type.

impl PartialEq for Size

fn eq(&self, other: &Size) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub for Size

type Output = Size

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl SubAssign<Size> for CellTreeStats

fn sub_assign(&mut self, rhs: Size)

Performs the -= operation.

impl SubAssign for Size

fn sub_assign(&mut self, rhs: Self)

Performs the -= operation.

impl Copy for Size

impl Eq for Size

impl StructuralPartialEq for Size
