Trait PrettyBuilder 

pub trait PrettyBuilder<'a, T> {
    // Required methods
    fn flat_alt<E>(self, inline: E) -> PrettyTree<'a, T>
       where E: Into<PrettyTree<'a, T>>;
    fn indent(self, indent: usize) -> PrettyTree<'a, T>;
    fn nest(self, offset: isize) -> PrettyTree<'a, T>;
}

The PrettyPrint trait is implemented by types that can be pretty-printed.

Required Methods

fn flat_alt<E>(self, inline: E) -> PrettyTree<'a, T>

where E: Into<PrettyTree<'a, T>>,

Acts as self when laid out on multiple lines and acts as that when laid out on a single line.

use pretty::{Arena, DocAllocator};

let arena = Arena::<()>::new();
let body = arena.line().append("x");
let doc = arena
    .text("let")
    .append(arena.line())
    .append("x")
    .group()
    .append(body.clone().flat_alt(arena.line().append("in").append(body)))
    .group();

assert_eq!(doc.1.pretty(100).to_string(), "let x in x");
assert_eq!(doc.1.pretty(8).to_string(), "let x\nx");

fn indent(self, indent: usize) -> PrettyTree<'a, T>

Acts as self when laid out on a single line and acts as that when laid out on multiple lines.

fn nest(self, offset: isize) -> PrettyTree<'a, T>

Increase the indentation level of this document.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
