Function run 

Source 
pub fn run()
Expand description

Parse std::env::args_os() and execute the selected bca subcommand. Intended to be called from the bca binary’s main, which is a one-liner over this function.

§Termination contract

This function may terminate the calling process rather than return. It is not a re-entrant library entry point:

  • clap argument-parsing failures bubble up through clap::Error::exit (exit 0 on --help / --version, exit 2 on usage errors).
  • User-input errors (invalid threshold spec, unreadable preproc data, missing --output parent directory, walk errors, mutually exclusive output-format combinations, broken-pipe writes, etc.) call process::exit(1) via internal die / die_io helpers.
  • The check subcommand calls process::exit(2) when any threshold is exceeded, reserving exit 1 for tool errors so CI can distinguish “metric regression” from “tool crashed”.

Hosts that call run will be torn down on any of those paths without unwinding. If you need to drive the same functionality from inside another process, use the big_code_analysis library crate directly instead of going through this entry point.
