Configuration for the GraphRAG system

Fields

output_dir: String

Output directory for storing graphs and data

chunk_size: usize

Chunk size for text processing

chunk_overlap: usize

Overlap between chunks

max_entities_per_chunk: Option<usize>

Maximum entities per chunk

top_k_results: Option<usize>

Top-k results for retrieval

similarity_threshold: Option<f32>

Similarity threshold for retrieval

approach: String

Pipeline approach: “semantic”, “algorithmic”, or “hybrid” Determines which implementation strategy to use for entity extraction and retrieval

embeddings: EmbeddingConfig

Vector embedding configuration

graph: GraphConfig

Graph construction parameters

text: TextConfig

Text processing settings

entities: EntityConfig

Entity extraction settings

retrieval: RetrievalConfig

Retrieval system configuration

parallel: ParallelConfig

Parallel processing configuration

ollama: OllamaConfig

Ollama integration configuration

gliner: GlinerConfig

GLiNER-Relex extractor configuration

enhancements: EnhancementsConfig

Latest enhancements configuration

auto_save: AutoSaveConfig

Auto-save configuration for workspace persistence

summarization: HierarchicalConfig

Hierarchical summarization configuration

zero_cost_approach: ZeroCostApproachConfig

Zero-cost approach configuration

advanced_features: AdvancedFeaturesConfig

Advanced features configuration (Phases 2-3)

suppress_progress_bars: bool

Suppress indicatif progress bars (use hidden draw target). Set to true when running inside a TUI to avoid corrupting the terminal.

Implementations

impl Config

pub fn load() -> Result<Self>

Load configuration with hierarchical merging (stub for when feature is disabled)

When the hierarchical-config feature is not enabled, this falls back to Config::default().

pub fn from_toml_file<P: AsRef<Path>>(path: P) -> Result<Self>

Load configuration from a TOML file with environment variable overrides

This is the preferred method for loading configuration from a specific file while still allowing environment variable overrides.

Example

use graphrag_core::Config;

let config = Config::from_toml_file("./my-config.toml")?;

pub fn from_file(path: &str) -> Result<Self>

Load configuration from a JSON file

pub fn to_file(&self, path: &str) -> Result<()>

Save configuration to a JSON file

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Config

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

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Validatable for Config

fn validate(&self) -> ValidationResult

Validate configuration with standard checks

fn validate_strict(&self) -> ValidationResult
