pub enum ValueError {
    NoValue,
    TypeMismatch {
        expected: DataType,
        actual: DataType,
    },
    ConversionFailed {
        from: DataType,

Value processing error type

Defines various error conditions that may occur during value operations.

Features

• Type mismatch error
• No value error
• Type conversion failure error
• Conversion error

Example

use common_rs::util::value::{ValueError, DataType};

let error = ValueError::NoValue;
assert_eq!(error.to_string(), "No value");

Trait Implementations

impl Debug for ValueError

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

Formats the value using the given formatter.

impl Display for ValueError

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

Formats the value using the given formatter.

impl Error for ValueError

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.
