Struct PropertySets 

pub struct PropertySets { /* private fields */ }

All property sets on an element, keyed by set name (Pset_WallCommon, and so on).

Implementations

impl PropertySets

pub fn new() -> Self

pub fn get(&self, set: &str, name: &str) -> Option<&PropertyValue>

pub fn set( &mut self, set: &str, name: &str, value: Option<PropertyValue>, ) -> Option<PropertyValue>

Set or clear a property. None removes it, and removes the set once it is empty so that set-then-unset leaves no trace — which is what makes command inversion exact.

Returns the previous value, which is what the inverse command is built from.

pub fn set_names(&self) -> impl Iterator<Item = &str>

pub fn iter(&self) -> impl Iterator<Item = (&str, &PropertySet)>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

Trait Implementations

impl Clone for PropertySets

fn clone(&self) -> PropertySets

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertySets

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

Formats the value using the given formatter.

impl Default for PropertySets

fn default() -> PropertySets

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PropertySets

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PropertySets

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for PropertySets

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
