Struct TokenAtlasPreview 

pub(crate) struct TokenAtlasPreview {
    edges: Vec<AtlasPreviewEdge>,
    truncated: bool,
    available: bool,
}

Bounded, non-interactive projection of resolved relations from the active project database.

Fields

edges: Vec<AtlasPreviewEdge>

Real resolved relations admitted within the node and edge ceilings.

truncated: bool

Whether a source page or a preview ceiling omitted additional relations.

available: bool

Whether the optional graph read completed successfully.

Implementations

impl TokenAtlasPreview

pub(crate) const fn empty() -> Self

Build an empty but available graph snapshot.

pub(crate) const fn unavailable() -> Self

Build the explicit state used when the optional graph read fails.

pub(crate) fn from_relations( relations: &[LogicalRelation], source_truncated: bool, ) -> Self

Retain only exact local resolutions from bounded database relation pages.

fn from_resolved_edges( relations: impl IntoIterator<Item = (String, String, GraphRelationKind)>, source_truncated: bool, ) -> Self

Build the bounded projection from already resolved stable identities.

fn node_count(&self) -> usize

Return the exact number of distinct nodes drawn by this preview.

Trait Implementations

impl Clone for TokenAtlasPreview

fn clone(&self) -> TokenAtlasPreview

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenAtlasPreview

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

Formats the value using the given formatter.

impl PartialEq for TokenAtlasPreview

fn eq(&self, other: &TokenAtlasPreview) -> 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.
