Struct datazoo::enum_bitmatrix::EnumBitMatrix

pub struct EnumBitMatrix<R: EnumSetType>(/* private fields */);

A bitset similar to BitMatrix, but with a fixed column and row count, indexed by R EnumSetType.

Implementations

impl<R: EnumSetType> EnumBitMatrix<R>

pub fn new(width: u32) -> Self

Create a new EnumBitMatrix.

Panics

When width * #Variant(T) > u32::MAX.

pub fn set_row(&mut self, row: R, iter: impl Iterator<Item = u32>)

Enable bits from iter for given row.

Note that items of iter not within bit_width are ignored, and already enabled bits stay enabled.

pub const fn bit_width(&self) -> u32

The width in bits of individual rows of this EnumBitMatrix.

pub fn row( &self, row: R, range: Range<u32> ) -> impl SortedIterator<Item = u32> + '_

Iterate over enabled bits in row, limited to provided range.

If the range doesn’t fit within 0..bit_width, it will be truncated to fit within that range.

pub const fn rows(&self, rows: EnumSet<R>, range: Range<u32>) -> Rows<'_, R>

Iterate over enabled bits in all rows, limited to provided range.

Rows is a sorted iterator.

Trait Implementations

impl<R: Clone + EnumSetType> Clone for EnumBitMatrix<R>

fn clone(&self) -> EnumBitMatrix<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R: EnumSetType> Debug for EnumBitMatrix<R>

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

Formats the value using the given formatter.

impl<R: PartialEq + EnumSetType> PartialEq for EnumBitMatrix<R>

fn eq(&self, other: &EnumBitMatrix<R>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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