Struct NumberTree 

pub struct NumberTree<V> { /* private fields */ }

A parsed number tree mapping integer keys to values of type V.

Implementations

impl<V> NumberTree<V>

pub fn parse<S: PdfSource, F>( root: &Object, store: &ObjectStore<S>, convert: F, ) -> DocResult<Self>

where F: Fn(&Object, &ObjectStore<S>) -> DocResult<V>,

Parse a number tree starting from the given root object.

The convert function transforms each value Object into a V. Traversal is fully iterative using an explicit stack.

pub fn get(&self, num: i64) -> Option<&V>

Look up a value by exact integer key.

pub fn floor(&self, num: i64) -> Option<&V>

Find the entry with the largest key less than or equal to num.

Corresponds to CPDF_NumberTree::GetFloor() in PDFium.

pub fn get_floor(&self, num: i64) -> Option<&V>

ADR-019 alias for floor().

Corresponds to CPDF_NumberTree::GetFloor() in PDFium.

pub fn entries(&self) -> &[(i64, V)]

Return all entries as a slice of (i64, V) pairs, sorted by key.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
