Struct Dict 

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

A dictionary. Keys are kept sorted, so iteration (and anything written from it) is deterministic. A repeated key keeps its last value.

Implementations

impl Dict

pub fn new() -> Dict

An empty dictionary.

pub fn get(&self, key: &[u8]) -> Option<&Object>

The value for key, if present. A null value counts as absent (ISO 32000-2 §7.3.7).

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

Sets key to value, returning the previous value.

pub fn remove(&mut self, key: &[u8]) -> Option<Object>

Removes key, returning its value.

pub fn contains_key(&self, key: &[u8]) -> bool

Whether key is present with a non-null value.

pub fn len(&self) -> usize

The number of entries.

pub fn is_empty(&self) -> bool

Whether there are no entries.

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

Entries in key order.

pub fn get_name(&self, key: &[u8]) -> Option<&[u8]>

The value for key if it is a name.

pub fn get_int(&self, key: &[u8]) -> Option<i64>

The value for key if it is an integer.

pub fn get_dict(&self, key: &[u8]) -> Option<&Dict>

The value for key if it is a dictionary (or a stream’s dictionary).

pub fn get_array(&self, key: &[u8]) -> Option<&[Object]>

The value for key if it is an array.

pub fn get_ref(&self, key: &[u8]) -> Option<ObjId>

The value for key if it is an indirect reference.

pub fn is_type(&self, ty: &[u8]) -> bool

Whether /Type is ty.

Trait Implementations

impl Clone for Dict

fn clone(&self) -> Dict

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dict

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Dict

fn default() -> Dict

Returns the “default value” for a type.

impl From<Dict> for Object

fn from(d: Dict) -> Object

Converts to this type from the input type.

impl FromIterator<(Name, Object)> for Dict

fn from_iter<I>(iter: I) -> Dict

where I: IntoIterator<Item = (Name, Object)>,

Creates a value from an iterator.

impl PartialEq for Dict

fn eq(&self, other: &Dict) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
