Trait Implementations

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

type Doc = RefDoc<'a, A>

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

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

Allocate an empty document.

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

Allocate a single newline.

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

Allocate a single space.

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

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

fn as_string<U: ToString>(&'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: Into<Doc<'a, Self::Doc, 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: Into<Doc<'a, Self::Doc, A>>,
    S: Into<Doc<'a, Self::Doc, 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].
