Trait Implementations

impl<'a, A> DocAllocator<'a, A> for RcAllocator

where A: 'a,

type Doc = RcDoc<'a, A>

fn alloc(&'a self, doc: Doc<'a, Self::Doc, A>) -> Self::Doc

fn alloc_column_fn( &'a self, f: impl Fn(usize) -> Self::Doc + 'a, ) -> <Self::Doc as DocPtr<'a, A>>::ColumnFn

fn alloc_width_fn( &'a self, f: impl Fn(isize) -> Self::Doc + 'a, ) -> <Self::Doc as DocPtr<'a, A>>::WidthFn

fn alloc_cow(&'a self, doc: BuildDoc<'a, Self::Doc, A>) -> Self::Doc

fn nil(&'a self) -> DocBuilder<'a, Self, A>

Allocate an empty document.

fn fail(&'a self) -> DocBuilder<'a, Self, A>

Fails document rendering immediately.

fn hardline(&'a self) -> DocBuilder<'a, Self, A>

Allocate a single hardline.

fn space(&'a self) -> DocBuilder<'a, Self, A>

fn line(&'a self) -> DocBuilder<'a, Self, A>

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

fn line_(&'a self) -> DocBuilder<'a, Self, A>

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

fn softline(&'a self) -> DocBuilder<'a, Self, A>

A softline acts like space if the document fits the page, otherwise like line

fn softline_(&'a self) -> DocBuilder<'a, Self, A>

A softline_ acts like nil if the document fits the page, otherwise like line_

fn as_string<U: Display>(&'a self, data: U) -> DocBuilder<'a, Self, A>

Allocate a document containing the text t.to_string().

fn text<U: Into<Cow<'a, str>>>(&'a self, data: U) -> DocBuilder<'a, Self, A>

Allocate a document containing the given text.

fn concat<I>(&'a self, docs: I) -> DocBuilder<'a, Self, A>

where I: IntoIterator, I::Item: Pretty<'a, Self, A>,

Allocate a document concatenating the given documents.

fn intersperse<I, S>(&'a self, docs: I, separator: S) -> DocBuilder<'a, Self, A>

where I: IntoIterator, I::Item: Pretty<'a, Self, A>, S: Pretty<'a, Self, A> + Clone,

Allocate a document that intersperses the given separator S between the given documents [A, B, C, ..., Z], yielding [A, S, B, S, C, S, ..., S, Z].

fn column( &'a self, f: impl Fn(usize) -> Self::Doc + 'a, ) -> DocBuilder<'a, Self, A>

Allocate a document that acts differently based on the position and page layout

fn nesting( &'a self, f: impl Fn(usize) -> Self::Doc + 'a, ) -> DocBuilder<'a, Self, A>

Allocate a document that acts differently based on the current nesting level

fn reflow(&'a self, text: &'a str) -> DocBuilder<'a, Self, A>

where Self: Sized, Self::Doc: Clone, A: Clone,

Reflows text inserting softline in place of any whitespace

impl<'a, A> Pretty<'a, RcAllocator, A> for RcDoc<'a, A>

where A: 'a,

fn pretty(self, allocator: &'a RcAllocator) -> DocBuilder<'a, RcAllocator, A>

Converts self into a document
