Struct Dict 

pub struct Dict(/* private fields */);

A dictionary object mapping names to objects.

Implementations

impl Dict

pub fn new() -> Dict

Creates an empty dictionary.

pub fn get(&self, key: &str) -> Option<&Object>

Looks up a value by key (without the leading solidus).

pub fn insert(&mut self, key: Name, value: Object) -> Option<Object>

Inserts a key/value pair, returning the previous value if any.

pub fn remove(&mut self, key: &str) -> Option<Object>

Removes a key, returning its value if present.

pub fn iter(&self) -> impl Iterator<Item = (&Name, &Object)>

Iterates over all key/value pairs (unordered).

pub fn len(&self) -> usize

Number of entries.

pub fn is_empty(&self) -> bool

Whether the dictionary has no entries.

pub fn get_int(&self, key: &str) -> Option<i64>

Typed lookup: integer value.

pub fn get_f64(&self, key: &str) -> Option<f64>

Typed lookup: numeric value as f64 (integers coerce).

pub fn get_name(&self, key: &str) -> Option<&Name>

Typed lookup: name value.

pub fn get_array(&self, key: &str) -> Option<&[Object]>

Typed lookup: array value.

pub fn get_dict(&self, key: &str) -> Option<&Dict>

Typed lookup: dictionary value.

pub fn get_ref(&self, key: &str) -> Option<ObjRef>

Typed lookup: indirect reference value.
