Struct msgpack_simple::ConversionError

pub struct ConversionError {
    pub original: MsgPack,
    pub attempted: &'static str,
}

An error that occurred when trying to access a field as a different type

The "as_type" functions of MsgPack can throw this error. It contains the original object and a string representation of the attempted conversion.

Fields

original: MsgPack

The original object, owned.

attempted: &'static str

A string that contains which type conversion was attempted.

Implementations

impl ConversionError

pub fn recover(self) -> MsgPack

Recovers the MsgPack object from the error

use msgpack_simple::MsgPack;

let float = MsgPack::Float(42.0);
let error = float.as_int().unwrap_err(); // trigger and capture an error
let recovered = error.recover();

assert!(recovered.is_float());
assert_eq!(recovered.as_float().unwrap(), 42.0);

Trait Implementations

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

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
