Struct msgpack_simple::ParseError

pub struct ParseError {
    pub byte: usize,
}

An error that occurred while parsing a binary as MsgPack

Fields

byte: usize

The byte where the error was found

Implementations

impl ParseError

pub fn offset(&self, value: usize) -> ParseError

Creates another error of the same type with a byte offset

use msgpack_simple::ParseError;

let error = ParseError { byte: 5 };
let other = error.offset(3);

assert_eq!(other.byte, 8);

pub fn offset_result<T>(
    result: Result<T, ParseError>,
    value: usize
) -> Result<T, ParseError>

Takes a result with ParseError as its error type and returns the same with a byte offset on the error

use msgpack_simple::ParseError;

let result: Result<(), ParseError> = Err(ParseError { byte: 39 });
let other = ParseError::offset_result(result, 3);

let error = other.unwrap_err();
assert_eq!(error.byte, 42);

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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
