Struct Banner 

pub struct Banner { /* private fields */ }

A rendered ASCII-art banner.

Banner is a lazy line iterator (per FR-053) from the caller’s perspective: row buffers are computed once during Figlet::render, and each call to next() on the iterator returned by Banner::lines yields one row.

Banner also implements core::fmt::Display; write!(stdout, "{banner}") drives the same lazy iterator and emits a trailing \n after the final line.

use rusty_figlet::{FigletBuilder, Font};

let banner = FigletBuilder::new()
    .font(Font::Standard)
    .build()
    .expect("build")
    .render("X")
    .expect("render");
// Iterate lazily; each .next() yields exactly one rendered row.
let mut it = banner.lines();
let _first = it.next();

Implementations

impl Banner

pub fn lines(&self) -> impl Iterator<Item = String> + '_

Return a lazy iterator yielding one rendered line per .next().

pub fn height(&self) -> u32

The font’s row count (height). Library callers occasionally want to know how many rows a banner contains without iterating.

pub fn is_empty(&self) -> bool

true when the banner produced no rendered rows (empty input).
