Struct 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)>

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
