Struct ChangeRun 

pub struct ChangeRun {
    pub y: u16,
    pub x0: u16,
    pub x1: u16,
}

A contiguous run of changed cells on a single row.

Used by the presenter to emit efficient cursor positioning. Instead of positioning for each cell, position once and emit the run.

Fields

y: u16

Row index.

x0: u16

Start column (inclusive).

x1: u16

End column (inclusive).

Implementations

impl ChangeRun

pub const fn new(y: u16, x0: u16, x1: u16) -> Self

Create a new change run.

pub const fn len(&self) -> u16

Number of cells in this run.

pub const fn is_empty(&self) -> bool

Check if this run is empty (should never happen in practice).

Trait Implementations

impl Clone for ChangeRun

fn clone(&self) -> ChangeRun

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeRun

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

Formats the value using the given formatter.

impl PartialEq for ChangeRun

fn eq(&self, other: &ChangeRun) -> 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.
