Struct Outline

pub struct Outline<'a> { /* private fields */ }

Writer for an outline dictionary.

This struct is created by Chunk::outline.

Implementations

impl<'a> Outline<'a>

pub fn first(&mut self, item: Ref) -> &mut Self

Write the /First attribute which points to the first item in the document’s outline.

pub fn last(&mut self, item: Ref) -> &mut Self

Write the /Last attribute which points to the last item in the document’s outline.

pub fn count(&mut self, count: i32) -> &mut Self

Write the /Count attribute. This tells the viewer how many outline elements (at all levels) are currently visible.

Panics if count is negative.

Methods from Deref<Target = Dict<'a>>

pub fn len(&self) -> i32

The number of written pairs.

pub fn is_empty(&self) -> bool

Whether no pairs have been written so far.

pub fn insert(&mut self, key: Name<'_>) -> Obj<'_>

Start writing a pair with an arbitrary value.

pub fn pair<T: Primitive>(&mut self, key: Name<'_>, value: T) -> &mut Self

Write a pair with a primitive value.

This is a shorthand for dict.insert(key).primitive(value).

pub fn pairs<'n, T: Primitive>( &mut self, pairs: impl IntoIterator<Item = (Name<'n>, T)>, ) -> &mut Self

Write a sequence of pairs with primitive values.
