Struct uucore::error::UIoError [−][src]
pub struct UIoError { /* fields omitted */ }Expand description
Wrapper type around std::io::Error.
The messages displayed by UIoError should match the error messages displayed by GNU
coreutils.
There are two ways to construct this type: with UIoError::new or by calling the
FromIo::map_err_context method on a std::io::Result or std::io::Error.
use uucore::error::{FromIo, UResult, UIoError, UCommonError}; use std::fs::File; use std::path::Path; let path = Path::new("test.txt"); // Manual construction let e: UIoError = UIoError::new( std::io::ErrorKind::NotFound, format!("cannot access '{}'", path.display()) ); let res: UResult<()> = Err(e.into()); // Converting from an `std::io::Error`. let res: UResult<File> = File::open(path).map_err_context(|| format!("cannot access '{}'", path.display()));
