Function build 

pub fn build(
    pyproject: Option<&str>,
    no_verify: bool,
    _postprocess_only: bool,
) -> Result<()>

Execute the build command to generate Python code from proto files.

This is the main entry point for the code generation pipeline. It performs the complete workflow: loading configuration, generating code, applying post-processing transformations, and running verification checks.

Arguments

• pyproject - Optional path to the pyproject.toml file. If None, uses “pyproject.toml”
• no_verify - If true, skips the verification step after generation
• _postprocess_only - If true, skips generation and only runs post-processing (experimental)

Returns

Returns Ok(()) on successful completion, or an error if any step fails.

Pipeline Steps

1. Configuration: Load and validate pyproject.toml settings
2. Generation: Run protoc or buf to generate Python files
3. Post-processing:
   • Create __init__.py files if configured
   • Convert absolute imports to relative imports
   • Add type checker suppression headers
4. Verification: Run import tests and optional type checking

Example

use python_proto_importer::commands::build;

// Standard build
build(None, false, false)?;

// Build without verification
build(None, true, false)?;

// Build with custom config file
build(Some("custom.toml"), false, false)?;
