Struct GraphPartitioner 

pub struct GraphPartitioner;

Graph Partitioner

Converts a PetCodeGraph into partitioned SQLite files.

Implementations

impl GraphPartitioner

pub fn partition( graph: &PetCodeGraph, prism_dir: &Path, root_name: Option<&str>, ) -> Result<Manifest, PartitionerError>

Partition a PetCodeGraph into SQLite partition files.

Arguments

• graph - The code graph to partition
• prism_dir - The .codeprysm directory path
• root_name - Optional root name for multi-root support (uses “default” if None)

Returns

A Manifest with file→partition mappings and partition→filename mappings.

pub fn partition_with_stats( graph: &PetCodeGraph, prism_dir: &Path, root_name: Option<&str>, ) -> Result<(Manifest, PartitioningStats), PartitionerError>

Partition a PetCodeGraph and return statistics.

Like partition() but also returns partitioning statistics.

pub fn partition_with_root_info( graph: &PetCodeGraph, prism_dir: &Path, root_info: RootInfo, ) -> Result<(Manifest, PartitioningStats), PartitionerError>

Partition a graph with a RootInfo structure for complete root metadata.

This variant accepts a pre-configured RootInfo for better control over git metadata and root type.

pub fn update_partition( graph: &PetCodeGraph, prism_dir: &Path, partition_id: &str, root_name: &str, ) -> Result<(), PartitionerError>

Update a single partition after file changes.

This is useful for incremental updates where only a few files changed.

Arguments

• graph - The updated code graph (containing only changed files)
• prism_dir - The .codeprysm directory path
• partition_id - The partition to update
• root_name - The root name

pub fn get_unique_files(graph: &PetCodeGraph) -> HashSet<String>

Get unique files from a graph.

Useful for determining which files are in a partition.
