Struct IncrementalUpdater 

pub struct IncrementalUpdater { /* private fields */ }

Manages incremental updates to the code graph.

Uses Merkle tree change detection to identify modified files, then selectively updates only the affected entities in the graph.

Example

use codeprysm_core::incremental::IncrementalUpdater;
use std::path::Path;

let mut updater = IncrementalUpdater::new(
    Path::new("./my-repo"),
    Path::new("./.codeprysm"),
    Path::new("./queries"),
)?;

// Perform incremental update
let result = updater.update_repository(false)?;
if result.has_changes() {
    println!("Updated {} files", result.changes.total_changes());
}

Implementations

impl IncrementalUpdater

pub fn new_with_embedded_queries( repo_path: &Path, prism_dir: &Path, ) -> Result<Self>

Create a new incremental updater using embedded queries.

This is the preferred constructor for production use as it doesn’t require external query files.

Arguments

• repo_path - Path to the repository being indexed
• prism_dir - Path to the .codeprysm directory containing partitions

Errors

Returns an error if the repository doesn’t exist.

pub fn with_embedded_queries( repo_path: &Path, prism_dir: &Path, exclusion_filter: ExclusionFilter, builder_config: BuilderConfig, ) -> Result<Self>

Create an updater with embedded queries and custom configuration.

pub fn new( repo_path: &Path, prism_dir: &Path, queries_dir: &Path, ) -> Result<Self>

Create a new incremental updater using query files.

Arguments

• repo_path - Path to the repository being indexed
• prism_dir - Path to the .codeprysm directory containing partitions
• queries_dir - Path to directory containing SCM query files

Errors

Returns an error if the repository or queries directory doesn’t exist.

pub fn with_config( repo_path: &Path, prism_dir: &Path, queries_dir: &Path, exclusion_filter: ExclusionFilter, builder_config: BuilderConfig, ) -> Result<Self>

Create an updater with custom configuration using query files.

pub fn load_graph_state(&mut self) -> Result<bool>

Load the existing graph state from partitions.

Returns

true if graph was loaded successfully, false if prism_dir doesn’t exist.

pub fn detect_repository_changes(&mut self) -> Result<ChangeSet>

Detect changes in the repository since last update.

Builds a new Merkle tree from the current filesystem state and compares it with the stored state.

pub fn update_repository(&mut self, force_rebuild: bool) -> Result<UpdateResult>

Perform incremental update of the repository.

Arguments

• force_rebuild - If true, rebuild everything regardless of changes

Returns

UpdateResult with information about what was updated.

pub fn graph(&self) -> Option<&PetCodeGraph>

Get a reference to the current graph.

pub fn graph_mut(&mut self) -> Option<&mut PetCodeGraph>

Get a mutable reference to the current graph.

pub fn merkle_tree(&self) -> &MerkleTree

Get the current Merkle tree.
