name	regenerate
description	Regenerate Rust test crates from TypeSpec specifications. Run this after modifying emitter source code or TypeSpec files under test/tsp/ to update generated output.

Regenerate the Rust test crates after modifying the emitter or contents under test/tsp/. This command can take several minutes to complete; wait for it to finish before proceeding.

Regenerate All Test Crates

cd packages/typespec-rust
pnpm run tspcompile

Regenerate Specific Test Crates

Use the --filter flag to regenerate only matching test crates (useful during development):

pnpm run tspcompile --filter=<pattern>

For example, to regenerate only tests containing "oauth":

pnpm run tspcompile --filter=oauth

Build Generated Rust Code

After regeneration, verify the generated Rust code compiles:

cd test
cargo build

What Regeneration Does

The tspcompile script:

1. Compiles TypeSpec specifications from @typespec/http-specs, @azure-tools/azure-http-specs, and local specs in test/tsp/
2. Generates Rust crates in test/spector/, test/sdk/, and test/other/
3. Updates the workspace Cargo.toml with all generated crates

Each generated crate includes:

• Cargo.toml — Rust package configuration
• src/lib.rs — Entry point (usually not regenerated to preserve customizations)
• src/generated/ — Generated Rust client code (fully regenerated)
• tests/ — Integration test files
