Struct Piece 

pub struct Piece<P = u64> {
    pub key: u64,
    pub rect: Rect,
    pub paint: P,
}

One piece of what a scroller paints: a line, a page, a caret. rect is where it paints with the content unscrolled (on screen plus the scroll), or on screen for a piece that does not move with the content; paint fingerprints its pixels, or is the scene that painted them (Painted).

Fields

key: u64

rect: Rect

paint: P

Trait Implementations

impl<P> Clone for Piece<P>

where P: Clone,

fn clone(&self) -> Piece<P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Debug for Piece<P>

where P: Debug,

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

Formats the value using the given formatter.

impl<P> PartialEq for Piece<P>

where P: PartialEq,

fn eq(&self, other: &Piece<P>) -> 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<P> Copy for Piece<P>

where P: Copy,

impl<P> StructuralPartialEq for Piece<P>
