cargo-vendormod-graph

name	cargo-vendormod-graph
description	Build, analyze, partition, and visualize Rust dependency graphs with cargo-vendormod. Use for global-graph commands.

Cargo-Vendormod Graph Operations

Build Graph

cargo run --bin cargo-vendormod -- BuildGraph \
  --workspace-path . \
  --output-dir ./graph_output \
  --include-dev \
  --include-build \
  --expand-features

Returns graph.json with nodes, edges, features, TOML structures, SCCs, and metrics.

Analyze Graph

cargo run --bin cargo-vendormod -- AnalyzeGraph \
  --input-path ./graph_output/graph.json \
  --output-dir ./analysis

Reports: node/edge counts, workspace members, direct/transitive/feature-gated deps, SCCs, diameter, average degree.

Visualize

cargo run --bin cargo-vendormod -- VisualizeGraph \
  --input-path ./graph_output/graph.json \
  --output-path ./graph.dot
dot -Tsvg graph.dot -o graph.svg

Partition Graph

cargo run --bin cargo-vendormod -- PartitionGraph \
  --input-path ./graph_output/graph.json \
  --partition-count 8 \
  --algorithm greedy \
  --output-dir ./partitions

Supported algorithms: greedy, kaminpar, metis, louvain, kernighanlin, spectral.

Key Library Types

• GlobalDependencyGraphBuilder — construct the graph
• GlobalDependencyGraph — result container (nodes, edges, metrics, topological orders)
• DependencyNode / DependencyEdge — graph elements
• PartitioningConfig / GraphPartition — partition inputs/outputs

Library Entry Points

use cargo_vendormod::global_dep_graph::{GlobalDependencyGraphBuilder, PartitioningConfig, PartitioningAlgorithm};

let mut builder = GlobalDependencyGraphBuilder::new(workspace_path);
builder.set_options(include_dev, include_build, expand_features);
let graph = builder.build_global_graph()?;
