Struct abortable_parser::Error

pub struct Error<C> { /* fields omitted */ }

The custom error type for use in Result::{Fail, Abort}. Stores a wrapped err that must implement Display as well as an offset and an optional cause.

Implementations

impl<C> Error<C>

pub fn new<D: Into<String>>(msg: D, ctx: Box<C>) -> Self

Constructs a new Error with an offset and no cause.

pub fn caused_by<'a, D: Into<String>>(
    msg: D,
    cause: Box<Self>,
    ctx: Box<C>
) -> Self

Constructs a new Error with an offset and a cause.

pub fn get_msg<'a>(&'a self) -> &str

Returns the msg.

pub fn get_cause<'a>(&'a self) -> Option<&'a Error<C>>

Returns Some(cause) if there is one, None otherwise.

pub fn get_context(&self) -> &C

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
