Enum pretty::Doc

pub enum Doc<'a, T: DocPtr<'a, A>, A = ()> {
    Nil,
    Append(T, T),
    Group(T),
    FlatAlt(T, T),
    Nest(isize, T),
    Line,
    OwnedText(Box<str>),
    BorrowedText(&'a str),
    SmallText(SmallText),
    Annotated(A, T),
    Union(T, T),
    Column(T::ColumnFn),
    Nesting(T::ColumnFn),
}

The concrete document type. This type is not meant to be used directly. Instead use the static functions on Doc or the methods on an DocAllocator.

The T parameter is used to abstract over pointers to Doc. See RefDoc and BoxDoc for how it is used

Methods

impl<'a, D, A> Doc<'a, D, A> where
    D: DocPtr<'a, A>, 

pub fn nil() -> Self

An empty document.

pub fn as_string<U: Display>(data: U) -> Self

The text t.to_string().

The given text must not contain line breaks.

pub fn hardline() -> Self

A single hardline.

pub fn text<U: Into<Cow<'a, str>>>(data: U) -> Self

The given text, which must not contain line breaks.

pub fn space() -> Self

impl<'a, D, A> Doc<'a, D, A> where
    D: StaticDoc<'a, A>, 

pub fn line() -> Self

A line acts like a \n but behaves like space if it is grouped on a single line.

pub fn line_() -> Self

Acts like line but behaves like nil if grouped on a single line

impl<'a, T, A> Doc<'a, T, A> where
    T: DocPtr<'a, A> + 'a, 

pub fn render<W: ?Sized>(&self, width: usize, out: &mut W) -> Result<()> where
    W: Write, 

Writes a rendered document to a std::io::Write object.

pub fn render_fmt<W: ?Sized>(&self, width: usize, out: &mut W) -> Result where
    W: Write, 

Writes a rendered document to a std::fmt::Write object.

pub fn render_raw<W: ?Sized>(
    &self,
    width: usize,
    out: &mut W
) -> Result<(), W::Error> where
    W: RenderAnnotated<A>, 

Writes a rendered document to a RenderAnnotated<A> object.

pub fn pretty<'d>(&'d self, width: usize) -> Pretty<'a, 'd, T, A>

Returns a value which implements std::fmt::Display

use pretty::{Doc, BoxDoc};
let doc = BoxDoc::<()>::group(
    BoxDoc::text("hello").append(Doc::line()).append(Doc::text("world"))
);
assert_eq!(format!("{}", doc.pretty(80)), "hello world");

impl<'a, T> Doc<'a, T, ColorSpec> where
    T: DocPtr<'a, ColorSpec> + 'a, 

pub fn render_colored<W>(&self, width: usize, out: W) -> Result<()> where
    W: WriteColor,
