harn_cli/cli/
mod.rs

1//! Top-level clap definition for the `harn` CLI.
2//!
3//! Per-subcommand arg structs live in their own modules under
4//! `crates/harn-cli/src/cli/`. The `Cli` and `Command` enum here only
5//! reference types via `pub(crate) use ...` re-exports so external
6//! consumers can keep using `crate::cli::TypeName` unchanged.
7//!
8//! Some variants of subcommand enums are reached only by destructuring
9//! the parent (`SubCommand::Foo(args) => ...`) and are never referenced
10//! by name from outside this module. Those types stay private to their
11//! per-subcommand module and are accessed through their parent enum.

182    harn run script.harn

184    harn run script.harn -- arg1 arg2   (script reads `argv` as list<string>)
185
186CONCURRENCY
187    Harn supports first-class concurrency primitives:
188      - spawn { ... }         — launch a task, return a handle
189      - parallel each LIST    — concurrent map
190      - parallel settle LIST  — concurrent map, collect Ok/Err
191      - parallel N            — N-way fan-out
192      - with { max_concurrent: N }  — cap in-flight workers
193      - channels, retry, select
194    https://harnlang.com/concurrency.html
195
196LLM THROTTLING
197    Providers can be rate-limited via `rpm:` in harn.toml / providers.toml
198    or via `HARN_RATE_LIMIT_<PROVIDER>=N`. Rate limits control throughput
199    (RPM); `max_concurrent` on `parallel` caps simultaneous in-flight jobs.
