Struct BlastRadius 

pub struct BlastRadius {
    pub direct: u32,
    pub transitive: u32,
    pub score: f32,
    pub tier: BlastTier,
}

Fields

direct: u32

Number of files that directly import this file (1 hop via Imports edges).

transitive: u32

Number of files that transitively import this file within TRANSITIVE_DEPTH, excluding direct importers. Deduplicated across all paths.

score: f32

Weighted score: direct + (transitive * TRANSITIVE_WEIGHT). Higher means more dangerous to modify.

tier: BlastTier

Categorical tier for agent-friendly consumption.

Implementations

impl BlastRadius

pub fn compute(file_key: &str, graph: &Graph) -> Self

Compute blast radius for a single file given the graph.

Uses neighbors_incoming with EdgeKind::Imports at depth 1 for direct count, and traverse_incoming at TRANSITIVE_DEPTH for the full transitive set. Transitive count excludes direct importers.

Prefer Self::compute_all for batch computation — it’s O(V+E) total vs O(N*(V+E)) when calling this in a loop.

pub fn compute_all( graph: &Graph, file_keys: &[String], ) -> HashMap<String, BlastRadius>

Compute blast radius for every file in the graph in a single pass.

Returns a map from file:<path> keys to their BlastRadius. Pre-computes the reverse adjacency list once, then runs bounded BFS per node. This avoids repeated edges_directed lookups in petgraph, reducing constant factors significantly on large graphs.

Trait Implementations

impl Clone for BlastRadius

fn clone(&self) -> BlastRadius

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlastRadius

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlastRadius

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BlastRadius

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

impl Serialize for BlastRadius

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
