Struct GraphOverlay 

pub struct GraphOverlay {
    pub nodes: BTreeMap<String, NodeOverlay>,
}

Per-node annotations for one rendering, keyed by node id.

Fields

nodes: BTreeMap<String, NodeOverlay>

Annotations keyed by node id; nodes absent here render plain.

Implementations

impl GraphOverlay

pub fn is_empty(&self) -> bool

No annotations at all — renderers then emit byte-identical plain output, so an empty overlay is indistinguishable from none.

Trait Implementations

impl Clone for GraphOverlay

fn clone(&self) -> GraphOverlay

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GraphOverlay

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

Formats the value using the given formatter.

impl Default for GraphOverlay

fn default() -> GraphOverlay

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for GraphOverlay

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for GraphOverlay

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
