Struct isotope_parser::prettyprint::DocBuilder [−]
pub struct DocBuilder<'a, D, A = ()>(pub &'a D, pub BuildDoc<'a, <D as DocAllocator<'a, A>>::Doc, A>)
where
D: DocAllocator<'a, A> + ?Sized;
Expand description
The DocBuilder
type allows for convenient appending of documents even for arena allocated
documents by storing the arena inline.

pub fn append<E>(self, that: E) -> DocBuilder<'a, D, A> where

pub fn append<E>(self, that: E) -> DocBuilder<'a, D, A> where
E: Into<BuildDoc<'a, <D as DocAllocator<'a, A>>::Doc, A>>,
Append the given document after this document.

E: Into<BuildDoc<'a, <D as DocAllocator<'a, A>>::Doc, A>>,
pub fn flat_alt<E>(self, that: E) -> DocBuilder<'a, D, A> where

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");
pub fn group(self) -> DocBuilder<'a, D, A>
pub fn group(self) -> DocBuilder<'a, D, A>
Mark this document as a group.
Groups are layed out on a single line if possible. Within a group, all basic documents with several possible layouts are assigned the same layout, that is, they are all layed out horizontally and combined into a one single line, or they are each layed out on their own line.
pub fn nest(self, offset: isize) -> DocBuilder<'a, D, A>
pub fn nest(self, offset: isize) -> DocBuilder<'a, D, A>
Increase the indentation level of this document.
pub fn annotate(self, ann: A) -> DocBuilder<'a, D, A>
pub fn union<E>(self, other: E) -> DocBuilder<'a, D, A> where
E: Into<BuildDoc<'a, <D as DocAllocator<'a, A>>::Doc, A>>,
pub fn align(self) -> DocBuilder<'a, D, A> where
DocBuilder<'a, D, A>: Clone,
pub fn align(self) -> DocBuilder<'a, D, A> where
DocBuilder<'a, D, A>: Clone,
Lays out self
so with the nesting level set to the current column
NOTE: The doc pointer type, D
may need to be cloned. Consider using cheaply cloneable ptr
like RefDoc
or RcDoc
use pretty::DocAllocator; let arena = pretty::Arena::<()>::new(); let doc = arena.text("lorem").append(arena.text(" ")) .append(arena.intersperse(["ipsum", "dolor"].iter().cloned(), arena.line_()).align()); assert_eq!(doc.1.pretty(80).to_string(), "lorem ipsum\n dolor");

DocBuilder<'a, D, A>: Clone,
pub fn hang(self, adjust: isize) -> DocBuilder<'a, D, A> where
DocBuilder<'a, D, A>: Clone,
Lays out self
with a nesting level set to the current level plus adjust
.
NOTE: The doc pointer type, D
may need to be cloned. Consider using cheaply cloneable ptr
like RefDoc
or RcDoc
use pretty::DocAllocator; let arena = pretty::Arena::<()>::new(); let doc = arena.text("prefix").append(arena.text(" ")) .append(arena.reflow("Indenting these words with nest").hang(4)); assert_eq!( doc.1.pretty(24).to_string(), "prefix Indenting these\n words with\n nest", );

DocBuilder<'a, D, A>: Clone,
pub fn indent(self, adjust: usize) -> DocBuilder<'a, D, A> where
DocBuilder<'a, D, A>: Clone,
Indents self
by adjust
spaces from the current cursor position
NOTE: The doc pointer type, D
may need to be cloned. Consider using cheaply cloneable ptr
like RefDoc
or RcDoc
use pretty::DocAllocator; let arena = pretty::Arena::<()>::new(); let doc = arena.text("prefix").append(arena.text(" ")) .append(arena.reflow("The indent function indents these words!").indent(4)); assert_eq!( doc.1.pretty(24).to_string(), " prefix The indent function indents these words!".trim_start(), );

f: impl Fn(isize) -> <D as DocAllocator<'a, A>>::Doc + 'a
) -> DocBuilder<'a, D, A> where
BuildDoc<'a, <D as DocAllocator<'a, A>>::Doc, A>: Clone,
Lays out self
and provides the column width of it available to f

may need to be cloned. Consider using cheaply cloneable ptr
like RefDoc
or RcDoc
use pretty::DocAllocator; let arena = pretty::Arena::<()>::new(); let doc = arena.text("prefix ") .append(arena.column(|l| { arena.text("| <- column ").append(arena.as_string(l)).into_doc() })); assert_eq!(doc.1.pretty(80).to_string(), "prefix | <- column 7");

Puts self
