harn-hostlib 0.10.140

//! Process abstraction used by the deterministic process tools.
//!
//! Production code spawns through [`spawn_process`], which dispatches to
//! the [`ProcessSpawner`] currently installed via
//! [`install_spawner`]. The default spawner ([`real::default_spawner`])
//! goes through `harn_vm::process_sandbox`. Tests install
//! [`mock::MockSpawner`] to drive process behaviour deterministically.
