Struct path_abs::Error

pub struct Error { /* fields omitted */ }

An error produced by performing an filesystem operation on a Path.

This error type is a light wrapper around std::io::Error. In particular, it adds the following information:

• The action being performed when the error occured
• The path associated with the IO error.

To maintain good ergonomics, this type has a impl From<Error> for std::io::Error defined so that you may use an io::Result with methods in this crate if you don't care about accessing the underlying error data in a structured form (the pretty format will be preserved however).

Examples

use path_abs::Error as PathError;
use path_abs::PathFile;

/// main function, note that you can use `io::Error`
fn try_main() -> Result<(), ::std::io::Error> {
    let lib = PathFile::new("src/lib.rs")?;
    Ok(())
}

Methods

impl Error

fn new(io_err: Error, action: &'static str, path: PathArc) -> Error

Create a new error when the path and action are known.

impl Error

fn path(&self) -> &Path

Returns the path associated with this error.

fn io_error(&self) -> &Error

Returns the std::io::Error associated with this errors.

fn action(&self) -> &str

Returns the action being performed when this error occured.
