Struct linefeed::terminal::Size

pub struct Size {
    pub lines: usize,
    pub columns: usize,
}

Represents the size of a terminal window

A valid size must not have zero lines or zero columns.

Fields

lines: usize

Number of lines in the terminal

columns: usize

Number of columns in the terminal

Implementations

impl Size

pub fn area(&self) -> usize

Returns the total number of cells in a terminal of the given size.

Panics

If lines * columns would overflow.

pub fn checked_area(&self) -> Option<usize>

Returns the total number of cells in a terminal of the given size.

Returns None in case of overflow.

Trait Implementations

impl Clone for Size

fn clone(&self) -> Size

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Size

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

Formats the value using the given formatter.

impl PartialEq<Size> for Size

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