Struct Surface 

pub struct Surface {
    pub size: SurfaceSize,
    pub cell_pixels: Option<CellPixels>,
}

What an application can observe about the surface it draws on.

An application needs these facts only where they carry application meaning — a viewport measured in cells, a layout that changes with the width. They reach update as a message and are read from the model by view, which receives no surface input of its own.

What the terminal can do with graphics is not here. Protocol capabilities select a runtime presentation strategy; they are not application state.

Fields

size: SurfaceSize

The drawable area, in cells.

cell_pixels: Option<CellPixels>

How large one cell is in pixels, where the terminal reports it.

Implementations

impl Surface

pub const fn new(columns: usize, rows: usize) -> Self

A surface of columns by rows cells, whose pixel geometry the terminal did not report.

Trait Implementations

impl Clone for Surface

fn clone(&self) -> Surface

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Surface

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

Formats the value using the given formatter.

impl Default for Surface

fn default() -> Surface

Returns the “default value” for a type.

impl Hash for Surface

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Surface

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