Enum slaps::Error

pub enum Error {
    ClapError(ClapError),
    ReadlineError(ReadlineError),
    MismatchedQuotes(usize),
    ExecutionError(ExecutionError),
}

Variant of all sub-types of errors returned by the library.

Variants

ClapError(ClapError)

Error while parsing the input using clap.

ReadlineError(ReadlineError)

Error while reading a line from standard input.

MismatchedQuotes(usize)

Mismatched quotes while parsing the input.

Contains the position of the first mismatched quote within the original input.

ExecutionError(ExecutionError)

Error returned by a command handler.

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

Formats the value using the given formatter.

impl Error for Error

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
