Struct ConversionError 

pub struct ConversionError {
    pub expected: &'static str,
    pub actual: String,
}

Error returned when a MontyObject cannot be converted to the requested Rust type.

Returned by the TryFrom implementations when an ObjectRef holds a different kind of value than the one requested.

Fields

expected: &'static str

The type name that was expected (e.g., “int”, “str”).

actual: String

The actual type name of the value (e.g., “list”, “NoneType”, or a class instance’s class name).

Implementations

impl ConversionError

pub fn new(expected: &'static str, actual: impl Into<String>) -> Self

Creates a new ConversionError with the expected and actual type names.

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>)
