Struct fs_extra::error::Error

pub struct Error {
    pub kind: ErrorKind,
    // some fields omitted
}

The error type for fs_extra operations with files and folder.

Errors mostly originate from the underlying OS, but custom instances of Error can be created with crafted error messages and a particular value of ErrorKind.

Fields

kind: ErrorKind

Type error

Implementations

impl Error

pub fn new(kind: ErrorKind, message: &str) -> Error

Create a new fs_extra error from a kind of error error as well as an arbitrary error payload.

#Examples

extern crate fs_extra;
use fs_extra::error::{Error, ErrorKind};

errors can be created from strings
let custom_error = Error::new(ErrorKind::Other, "Other Error!");
// errors can also be created from other errors
let custom_error2 = Error::new(ErrorKind::Interrupted, custom_error);

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Error for Error

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
