Function run 

pub fn run<R: Read, W: Write, E: Write>(
    cli: Cli,
    io: &mut Io<R, W, E>,
) -> Result<(), FaceError>

Library entry point with explicit I/O.

The binary’s main wraps the locked OS handles into Io and passes them in here; tests use in-memory slices and buffers.

Errors

Surfaces every FaceError variant raised inside the pipeline. Conflicting flags surface as FaceError::ConflictingFlags; detection ambiguity as FaceError::AmbiguousDetection.

Examples

use face_cli::{Io, cli};
use clap::Parser;

let parsed = cli::Cli::parse_from(["face"]);
let mut io = Io::new(std::io::empty(), Vec::<u8>::new(), Vec::<u8>::new());
let _ = face_cli::run(parsed, &mut io);
