Struct GraphRAGConfig 

pub struct GraphRAGConfig {
    pub max_entities_per_doc: usize,
    pub max_relations_per_doc: usize,
    pub community_max_levels: usize,
    pub max_context_tokens: Option<usize>,
    pub entity_matcher: Option<Box<dyn EntityMatcher>>,
}

Configuration for GraphRAG.

Fields

max_entities_per_doc: usize

max_relations_per_doc: usize

community_max_levels: usize

max_context_tokens: Option<usize>

Maximum number of tokens for context in query prompts. When set, community summaries or subgraph context is truncated to fit.

entity_matcher: Option<Box<dyn EntityMatcher>>

Custom entity matcher for local/hybrid queries. When None, uses the default KeywordMatcher.

Implementations

impl GraphRAGConfig

pub fn new() -> Self

pub fn with_max_entities_per_doc(self, n: usize) -> Self

pub fn with_max_relations_per_doc(self, n: usize) -> Self

pub fn with_community_max_levels(self, n: usize) -> Self

pub fn with_max_context_tokens(self, tokens: usize) -> Self

Sets the maximum number of tokens for context in query prompts.

When set, community summaries (Global/Hybrid) or subgraph context (Local/Hybrid) are truncated from lowest-priority items to fit within this budget.

pub fn with_entity_matcher(self, matcher: Box<dyn EntityMatcher>) -> Self

Sets a custom entity matcher for local/hybrid queries.

When set, the matcher is used instead of the default keyword-based matching to find relevant entities.

Trait Implementations

impl Default for GraphRAGConfig

fn default() -> Self

Returns the “default value” for a type.
