pub struct TerminalSize {
    pub columns: usize,
    pub rows: usize,
    pub pixels: Option<PixelSize>,
}

The size of a terminal.

Fields

rows: usize

The height of the terminal, in lines.

pixels: Option<PixelSize>

The size in pixels, if available.

Implementations

impl TerminalSize

pub fn from_env() -> Option<Self>

Get terminal size from $COLUMNS and $LINES.

Do not assume any knowledge about window size.

pub fn from_terminal() -> Option<Self>

Detect the terminal size by querying the underlying terminal.

On unix this issues a ioctl to the controlling terminal.

On Windows this uses the term_size crate which does some magic windows API calls.

pub fn detect() -> Option<Self>

Detect the terminal size.

Get the terminal size from the underlying TTY, and fallback to $COLUMNS and $LINES.
