Struct text_terminal::ScreenSize

pub struct ScreenSize {
    pub num_columns: Column,
    pub num_rows: Row,
}

The size of a terminal screen, expressed as the number of columns (x dimension) by the number of rows (y dimension).

The default screen size is 80 columns by 25 rows.

Fields

num_columns: Column

The width of the screen viewport in number of columns (x dimension).

num_rows: Row

The height of the screen viewport in number of rows (y dimension).

Implementations

impl ScreenSize

pub fn last_row(&self) -> Row

Returns the index of the final Row, which is num_rows - 1.

pub fn last_column(&self) -> Column

Returns the index of the final Column, which is num_columns - 1.

Trait Implementations

impl Clone for ScreenSize

fn clone(&self) -> ScreenSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScreenSize

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

Formats the value using the given formatter.

impl Default for ScreenSize

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<ScreenSize> for ScreenSize

fn eq(&self, other: &ScreenSize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
