A cross-platform library for running child processes and building pipelines.
duct wants to make shelling out in Rust as easy and flexible as it
is in Bash. It also takes care of tricky
inconsistencies
in the way different platforms shell out. And it's a cross-language
library; the original
implementation is in Python,
with an identical API.
duct uses os_pipe
internally, and the docs for that one include a big
example that uses more than a
dozen lines of code to read both stdout and stderr from a child
process. duct can do that in one line:
```rust use duct::sh;
let output = sh("echo foo && echo bar >&2").stderrtostdout().read().unwrap();
assert!(output.split_whitespace().eq(vec!["foo", "bar"])); ```
