Struct Block 

pub struct Block {
    pub lines: Vec<String>,
    pub width: usize,
    pub baseline: usize,
}

A 2D text block where every line has equal width. Supports vertical stacking, horizontal juxtaposition with baseline alignment, and delimiter wrapping — building blocks for block-mode Unicode rendering of matrices, fractions, delimited expressions, etc.

Fields

lines: Vec<String>

width: usize

baseline: usize

Implementations

impl Block

pub fn from(s: &str) -> Block

pub fn empty() -> Block

pub fn render(&self) -> String

pub fn height(&self) -> usize

pub fn width(&self) -> usize

pub fn baseline(&self) -> usize

pub fn pad_to(&self, target_width: usize) -> Block

pub fn center(&self, target_width: usize) -> Block

pub fn above(&self, other: &Block) -> Block

Vertical concatenation. The narrower block is padded to match width.

pub fn beside(&self, other: &Block) -> Block

Horizontal concatenation, aligning blocks at their baseline positions.

pub fn append_left(&self, label: &Block) -> Block

pub fn append_right(&self, label: &Block) -> Block

pub fn enclose(&self, left: &str, right: &str) -> Block

Enclose every line with left and right delimiters.

pub fn row(cells: &[String], widths: &[usize], gap: &str) -> Block

Build a single-row block from cell text strings, each padded to the corresponding column width, then joined by gap.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Eq for Block

impl PartialEq for Block

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

Equality operator ==.
