Struct LeidenConfigInput 

pub struct LeidenConfigInput {
    pub seed: u64,
    pub gamma: f64,
    pub iterations: usize,
    pub quality: QualityFunctionInput,
    pub edge_weights: Option<BTreeMap<String, f64>>,
    pub min_compression_ratio: f64,
    pub max_recursion_depth: u32,
}

Leiden algorithm configuration for pure-compute callers.

Examples

use sdivi_core::input::{LeidenConfigInput, QualityFunctionInput};

let cfg = LeidenConfigInput::default();
assert_eq!(cfg.seed, 42);
assert_eq!(cfg.min_compression_ratio, 0.1);

Fields

seed: u64

Random seed for deterministic results.

gamma: f64

Resolution parameter (CPM only; ignored for Modularity).

iterations: usize

Maximum outer-loop iterations.

quality: QualityFunctionInput

Quality function to optimise.

edge_weights: Option<BTreeMap<String, f64>>

Per-edge weights for weighted Leiden; None = 1.0 for all edges. Keys: "source\x00target" (NUL-sep, source < target); use crate::input::edge_weight_key.

min_compression_ratio: f64

Stop recursive Leiden when an aggregation level would compress the graph by less than this fraction of nodes. Must be in [0.0, 1.0). Default 0.1.

max_recursion_depth: u32

Hard cap on Leiden recursion depth. Default 32.

Trait Implementations

impl Clone for LeidenConfigInput

fn clone(&self) -> LeidenConfigInput

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeidenConfigInput

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

Formats the value using the given formatter.

impl Default for LeidenConfigInput

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LeidenConfigInput

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LeidenConfigInput

fn eq(&self, other: &LeidenConfigInput) -> 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 LeidenConfigInput

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
