Struct SampleContext 

pub struct SampleContext<'a> {
    pub node: &'a GraphNode,
    pub neighbors: Vec<NeighborRef<'a>>,
    pub content: Option<&'a str>,
    pub annotations: &'a HashMap<String, Value>,
    pub graph_metadata: &'a HashMap<String, String>,
}

Local context provided to a Sampler during computation.

Gathers everything known about a single node at the time of sampling: structural position, optional content, previously-computed annotations, and the edges connecting it to its neighbors.

Fields

node: &'a GraphNode

The node being sampled.

neighbors: Vec<NeighborRef<'a>>

Direct neighbors (both incoming and outgoing edges resolved to nodes).

content: Option<&'a str>

Source file content, when available and requested.

annotations: &'a HashMap<String, Value>

Previously-computed artifacts attached to this node (keyed by sampler id). Enables sampler composition: earlier samplers deposit artifacts that later samplers can read.

graph_metadata: &'a HashMap<String, String>

Graph-level metadata (project name, workspace root, etc.).

Trait Implementations

impl<'a> Clone for SampleContext<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for SampleContext<'a>

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

Formats the value using the given formatter.
