Struct Bitmap

pub struct Bitmap { /* private fields */ }

A bitmap with room for 8 bits used by Frame to create a compact frame buffer

Implementations

impl Bitmap

pub const fn new(input: u8, nbits: usize) -> Self

Create a new bitmap with initial input and number of bits

pub const fn empty(nbits: usize) -> Self

Create an empty bitmap with nbits bits

pub fn set(&mut self, bit: usize)

Set bit n in bitmap

pub fn clear_all(&mut self)

Clear all bits in bitmap

pub fn clear(&mut self, bit: usize)

Clear bit n in bitmap

pub fn is_set(&self, bit: usize) -> bool

Check if bit n is set in bitmap

pub fn shift_left(&mut self, nbits: usize)

Shift left by nbits bits

pub fn shift_right(&mut self, nbits: usize)

Shift right by nbits bits

pub fn or(&mut self, other: &Bitmap)

Logical OR with another bitmap

pub fn and(&mut self, other: &Bitmap)

Logical AND with another bitmap

Trait Implementations

impl Clone for Bitmap

fn clone(&self) -> Bitmap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bitmap

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

Formats the value using the given formatter.

impl PartialEq for Bitmap

fn eq(&self, other: &Bitmap) -> 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 Copy for Bitmap

impl StructuralPartialEq for Bitmap
