Struct CommandConfig 

pub struct CommandConfig {
    pub description: Option<String>,
    pub entry: Option<String>,
    pub docker: Option<String>,
    pub ddp: Option<DdpConfig>,
    pub training: Option<TrainingConfig>,
    pub output: Option<OutputConfig>,
    pub commands: BTreeMap<String, CommandSpec>,
    pub arg_name: Option<String>,
    pub schema: Option<Schema>,
    pub compile: Option<bool>,
}

Sub-command fdl.yaml (e.g., ddp-bench/fdl.yaml).

Identical shape to ProjectConfig but with an executable entry: and optional structured config sections (ddp/training/output) that inline preset commands can override.

Fields

description: Option<String>

entry: Option<String>

docker: Option<String>

Docker compose service name. When set, entry is wrapped in docker compose run --rm <service> bash -c "cd <workdir> && <entry> <args>".

ddp: Option<DdpConfig>

training: Option<TrainingConfig>

output: Option<OutputConfig>

commands: BTreeMap<String, CommandSpec>

Nested commands — inline presets of this config’s entry, standalone run scripts, or path pointers to child fdl.yml files.

arg_name: Option<String>

Help-only placeholder name for the first-positional slot when commands: holds presets. Defaults to “preset”. Pure UX — it does not affect dispatch (presets are always looked up by name). Useful to match domain vocabulary, e.g. arg-name: recipe or arg-name: target.

schema: Option<Schema>

Inline interim schema (before <entry> --fdl-schema is implemented). Drives help rendering, validation, and completions.

compile: Option<bool>

Opt-in flag for cargo-entry schema probing. Cargo entries are auto-skipped from probing because cargo run --fdl-schema triggers a full compile (unacceptable latency for -h). Setting compile: true declares “I’m fine with the first-run compile cost — probe my binary for its real schema.” Subsequent invocations use the mtime-keyed cache and pay no compile cost. Absent or false keeps the default skip behavior, so the inline yml schema (if any) stays the source of truth.
