Implementations

impl VllmInstaller

pub fn new(config: VllmConfig) -> Self

Create a new vLLM installer with the given config.

pub fn with_defaults() -> Self

Create with default config.

pub fn dependencies(&self) -> &[&str]

vLLM depends on PyTorch.

pub fn validate_dependencies(&self, installed_components: &[&str]) -> Result<()>

Validate that all dependencies are satisfied.

pub fn detect_rocm_mm(&self) -> String

Detect ROCm major.minor version.

pub fn rocm_index_url(&self) -> String

Get the ROCm PyTorch wheel index URL.

pub fn vllm_wheels_url(&self) -> &'static str

Get the vLLM ROCm wheels extra index URL.

pub fn rocm_build_env(&self, rocm_env: &RocmEnv) -> Vec<(String, String)>

Construct the ROCm build environment variables.

pub fn build_vllm_install_command(&self) -> ShellCommand

Construct the pip install command for vLLM from ROCm wheels.

The original script uses: pip install --no-cache-dir --no-deps vllm --extra-index-url https://wheels.vllm.ai/rocm/

pub fn build_deps_install_command(&self) -> ShellCommand

Construct the pip install command for vLLM dependencies.

Installs the core dependencies needed by vLLM (excluding torch and xformers).

pub fn build_versioned_deps_command(&self) -> ShellCommand

Construct the pip install command for vLLM versioned dependencies.

These have specific version pins from the original script.

pub fn triton_cache_env(&self) -> Vec<(String, String)>

Construct the Triton cache environment setup command.

Sets up writable cache directories for Triton kernel compilation.

pub fn build_force_reinstall_command(&self) -> ShellCommand

Construct the force-reinstall command for vLLM wheel repair.

pub fn build_source_rebuild_command(&self) -> ShellCommand

Construct the source rebuild command for vLLM.

Used as a fallback when wheel install fails.
