Struct RowMask 

pub struct RowMask(/* private fields */);

A set of the display’s rows, a bit each.

Implementations

impl RowMask

pub fn insert(&mut self, y: i32)

Adds row y (a row off the display adds nothing).

pub fn contains(&self, y: i32) -> bool

Whether it holds row y.

pub fn count(&self) -> u32

How many rows it holds.

pub fn is_empty(&self) -> bool

Whether it holds none.

pub fn rows(&self) -> impl Iterator<Item = i32> + '_

The rows it holds, top to bottom.
