pub struct LiveError {
    pub line: usize,
    pub column: usize,
    pub length: usize,
    pub message: String,
}

Fields

line: usize

column: usize

The column of the first character, from 1.

length: usize

How many characters it covers, at least 1.

message: String

What is wrong.

impl Eq for LiveError

impl Error for LiveError

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

Returns 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
