Struct DataMap 

pub struct DataMap { /* private fields */ }

Untyped data map: maps (node_id, key) → DataValue. This is the Rust-side of the JS node.data map. When a JS plugin runs after a Rust plugin, this gets synced to the JS DataMap.

Implementations

impl DataMap

pub fn new() -> Self

pub fn set(&mut self, node_id: u32, key: &str, value: DataValue)

pub fn get(&self, node_id: u32, key: &str) -> Option<&DataValue>

pub fn remove(&mut self, node_id: u32, key: &str)

pub fn has(&self, node_id: u32, key: &str) -> bool

pub fn entries_for_node( &self, node_id: u32, ) -> impl Iterator<Item = (&str, &DataValue)>

Iterate all entries for a given node_id

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl Debug for DataMap

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

Formats the value using the given formatter.

impl Default for DataMap

fn default() -> DataMap
