Struct GraphView 

pub struct GraphView<'a> {
    pub ids: &'a IdMap,
    pub syms: &'a Interner,
    pub labels: &'a [u32],
    pub props: &'a ColumnStore,
    pub topo: &'a Topology,
    pub edge_props: &'a EdgeProps,
    pub mask: Option<&'a HashSet<u32>>,
}

Read-only twin of GraphMut. Holds only borrowed graph state.

Fields

ids: &'a IdMap

syms: &'a Interner

labels: &'a [u32]

props: &'a ColumnStore

topo: &'a Topology

edge_props: &'a EdgeProps

mask: Option<&'a HashSet<u32>>

Optional query-scoped node visibility set. None = all nodes visible. When Some(set), only dense ids present in set are accessible.

Implementations

impl<'a> GraphView<'a>

pub fn visible(&self, id: u32) -> bool

Returns true if id is visible under the current mask. Always true when no mask is set.

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

pub fn key_of(&self, id: u32) -> &str

pub fn label_of(&self, id: u32) -> Option<&str>

pub fn nodes_with_label(&self, label: &str) -> Vec<u32>

pub fn prop(&self, id: u32, field: &str) -> Option<&Value>
