Struct RoleMap

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

Writer for a role map dictionary. PDF 1.4+

This struct is created by StructTreeRoot::role_map.

Implementations

impl<'a> RoleMap<'a>

pub fn insert(&mut self, name: Name<'_>, role: StructRole) -> &mut Self

Write an entry mapping a custom name to a pre-defined role.

Methods from Deref<Target = TypedDict<'a, Name<'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 pair(&mut self, key: Name<'_>, value: T) -> &mut Self

where T: Primitive,

Write a key-value pair.

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

where T: Primitive,

Write a sequence of key-value pairs.

pub fn insert<'b>(&'b mut self, key: Name<'_>) -> <T as Rewrite<'_>>::Output

where T: Writer<'a> + Rewrite<'b>,

Start writing a pair with the typed writer.

Returns T but with its lifetime rewritten from 'a to 'b.
