Struct DegreeSampler 

pub struct DegreeSampler;

A sampler that counts each node’s direct neighbors (degree centrality). Demonstrates the pattern and is useful as a lightweight structural signal.

Trait Implementations

impl Sampler for DegreeSampler

fn id(&self) -> &str

Stable identifier (used as key in annotation maps and persistence).

fn selector(&self) -> NodeSelector

Which nodes this sampler operates on.

fn compute( &self, ctx: &SampleContext<'_>, ) -> Result<Option<Value>, SamplerError>

Compute the artifact for a single node. Return Ok(None) to skip a node without error.

fn sample( &self, graph: &SourceCodeGraph, annotations: &AnnotationMap, ) -> Result<SampleResult, SamplerError>

Run the full sampling pass over a graph.
