pub struct ExitCode(pub i32);
Expand description
A special error type that does not print any message when returned from
uumain
. Especially useful for porting utilities to using UResult
.
There are two ways to construct an ExitCode
:
use uucore::error::{ExitCode, UResult};
let res: UResult<()> = Err(ExitCode(1).into());
let res: UResult<()> = Err(1.into());
This type is especially useful for a trivial conversion from utils returning i32
to
returning UResult
.
