Enum LayoutScope 

pub enum LayoutScope {
    All,
    Nodes {
        nodes: BTreeSet<NodeId>,
    },
}

Which nodes a layout request should include.

Variants

All

Include all non-hidden nodes.

Nodes

Include only these nodes. Hidden nodes are still ignored.

Fields

nodes: BTreeSet<NodeId>

Implementations

impl LayoutScope

pub fn from_footprint( graph: &Graph, footprint: &GraphMutationFootprint, ) -> LayoutScope

Derives a conservative node scope from a graph mutation footprint and the current graph.

Direct node changes are included. Port and edge changes expand to their owning endpoint nodes when that information is available in the current graph snapshot. Node ids that no longer exist in the supplied graph are omitted.

pub fn from_transaction(graph: &Graph, tx: &GraphTransaction) -> LayoutScope

Derives a conservative node scope from a transaction and the current graph.

pub fn is_empty(&self) -> bool

Returns true when this scope selects no nodes.

pub fn nodes(&self) -> Option<&BTreeSet<NodeId>>

Returns selected nodes when this is a node-limited scope.

Trait Implementations

impl Clone for LayoutScope

fn clone(&self) -> LayoutScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutScope

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

Formats the value using the given formatter.

impl Default for LayoutScope

fn default() -> LayoutScope

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LayoutScope

fn deserialize<__D>( __deserializer: __D, ) -> Result<LayoutScope, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LayoutScope

impl PartialEq for LayoutScope

fn eq(&self, other: &LayoutScope) -> 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 LayoutScope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
