Struct Config 

pub struct Config {
    pub models: HashMap<String, ModelConfig>,
    pub policy: PolicyConfig,
    pub port: u16,
    pub metrics_port: u16,
    pub admin_port: Option<u16>,
    pub vllm_command: String,
    pub checkpoint: Option<CheckpointConfig>,
    pub warmup: bool,
}

Top-level configuration

Fields

models: HashMap<String, ModelConfig>

Models to manage

policy: PolicyConfig

Switch policy configuration

port: u16

Proxy port

metrics_port: u16

Metrics port (0 to disable)

admin_port: Option<u16>

Admin/control API port (None to disable)

vllm_command: String

Command to use for spawning vLLM processes (default: “vllm”) Can be overridden for testing with mock-vllm

checkpoint: Option<CheckpointConfig>

CRIU/CUDA checkpoint configuration. Required when any model uses CudaSuspend or Checkpoint process strategy.

warmup: bool

Whether to warm up all models before accepting traffic.

When enabled, the daemon sequentially starts each model, runs a warmup inference, then sleeps it using the model’s configured eviction policy. After warmup, every model is in its warm sleeping state, so the first real request triggers a fast wake rather than a cold start.

Implementations

impl Config

pub async fn from_file(path: &Path) -> Result<Self>

Load configuration from a JSON file

pub fn validate(&self)

Validate configuration, warning about common misconfigurations.

Checks that models using CudaSuspend or Checkpoint process strategies with tensor parallelism have the required vLLM flags.

pub fn build_onwards_targets(&self) -> Result<Targets>

Build onwards Targets from model configs
