Struct Line 

pub struct Line {
    pub spans: Vec<Span>,
}

A horizontal sequence of Spans rendered as a single line.

Examples

use retroglyph_core::text::{Line, Span};
use retroglyph_core::color::Style;
use retroglyph_core::color::Color;

let line = Line::from(vec![
    Span::raw("HP: "),
    Span::styled("100", Style::new().fg(Color::GREEN)),
]);
assert_eq!(line.width(), 7);

Fields

spans: Vec<Span>

The spans that make up this line.

Implementations

impl Line

pub fn new() -> Line

Creates an empty line.

pub fn raw(content: impl Into<String>) -> Line

Creates a line from a single unstyled string.

pub fn width(&self) -> usize

Returns the total display width of this line in terminal columns.

Accounts for wide characters (CJK, emoji) that occupy two columns.

Trait Implementations

impl Clone for Line

fn clone(&self) -> Line

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Line

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

Formats the value using the given formatter.

impl Default for Line

fn default() -> Line

Returns the “default value” for a type.

impl Eq for Line

impl From<&str> for Line

fn from(s: &str) -> Line

Converts to this type from the input type.

impl From<Span> for Line

fn from(span: Span) -> Line

Converts to this type from the input type.

impl From<String> for Line

fn from(s: String) -> Line

Converts to this type from the input type.

impl From<Vec<Span>> for Line

fn from(spans: Vec<Span>) -> Line

Converts to this type from the input type.

impl PartialEq for Line

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