start_command/
mod.rs

1//! start-command library
2//!
3//! Provides command execution with isolation, substitution, and failure handling.
4
5// `println!` and friends that drop write errors instead of panicking. Rust
6// ignores SIGPIPE, so printing into a closed pipe (`start --version | head -1`)
7// fails with EPIPE; like the JavaScript edition, start keeps running and exits
8// with its own code (issue #222). Defined before the modules, these shadow the
9// std macros in all of them; the binary imports them from the crate root.
