Struct bit_matrix::submatrix::BitSubMatrixMut

pub struct BitSubMatrixMut<'a> { /* fields omitted */ }

Mutable access to a range of matrix's rows.

Methods

impl<'a> BitSubMatrixMut<'a>

pub fn new(slice: &mut [Block], row_bits: usize) -> BitSubMatrixMut

Returns a new BitSubMatrixMut.

pub unsafe fn from_raw_parts(
    ptr: *mut Block,
    rows: usize,
    row_bits: usize
) -> Self

Forms a BitSubMatrix from a pointer and dimensions.

pub fn set(&mut self, row: usize, col: usize, enabled: bool)

Sets the value of a bit.

Panics

Panics if (row, col) is out of bounds.

pub fn sub_matrix(&self, range: Range<usize>) -> BitSubMatrix

Returns a slice of the matrix's rows.

pub fn split_at(
    &self,
    row: usize
) -> (BitSubMatrix, &BitVecSlice, BitSubMatrixMut)

Given a row's index, returns a slice of all rows above that row, a reference to said row, and a slice of all rows below.

Functionally equivalent to (self.sub_matrix(0..row), &self[row], self.sub_matrix(row..self.num_rows())).

pub fn split_at_mut(
    &mut self,
    row: usize
) -> (BitSubMatrixMut, &mut BitVecSlice, BitSubMatrixMut)

Given a row's index, returns a slice of all rows above that row, a reference to said row, and a slice of all rows below.

pub fn transitive_closure(&mut self)

Computes the transitive closure of the binary relation represented by the matrix.

Uses the Warshall's algorithm.

pub fn reflexive_closure(&mut self)

Computes the reflexive closure of the binary relation represented by the matrix.

pub fn iter_mut(
    &mut self
) -> Map<ChunksMut<Block>, fn(_: &mut [Block]) -> &mut BitVecSlice>

Iterates over the matrix's rows in the form of mutable slices.
