Error information for unquote operations

This error contains diagnostics from an unquote-operation. In particular, it contains the character and byte offsets of the cursor where the error originated.

Examples

let quote = "'Hello' 'World!";
let res = r_shquote::unquote(quote).unwrap_err();

match res {
    r_shquote::UnquoteError::UnterminatedSingleQuote { char_cursor: x, .. } |
    r_shquote::UnquoteError::UnterminatedDoubleQuote { char_cursor: x, .. } => {
        println!("Input: {}", quote);
        println!("       {}^--- unterminated quote", " ".repeat(x));
    },
}

Trait Implementations

impl Clone for UnquoteError

fn clone(&self) -> UnquoteError

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnquoteError

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

Formats the value using the given formatter.

impl Display for UnquoteError

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

Formats the value using the given formatter.

impl Error for UnquoteError

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

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

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting
