Enum ValueConversionError 

pub enum ValueConversionError {
    TypeMismatch {
        expected: ValueType,
        actual: ValueType,
    },
    MissingField(String),
    InvalidValue(String),
    OutOfRange(String),
    Custom(String),
}

Error that occurs during value conversion.

Variants

TypeMismatch

Type mismatch during conversion.

Fields

expected: ValueType

The expected type.

actual: ValueType

The actual type.

MissingField(String)

Missing required field in map.

InvalidValue(String)

Invalid value for the target type.

OutOfRange(String)

Out of range for numeric conversion.

Custom(String)

Custom conversion error.

Implementations

impl ValueConversionError

pub fn type_mismatch(expected: ValueType, actual: ValueType) -> Self

Create a type mismatch error.

pub fn missing_field(field: impl Into<String>) -> Self

Create a missing field error.

pub fn invalid_value(msg: impl Into<String>) -> Self

Create an invalid value error.

pub fn out_of_range(msg: impl Into<String>) -> Self

Create an out of range error.

pub fn custom(msg: impl Into<String>) -> Self

Create a custom error.

Trait Implementations

impl Clone for ValueConversionError

fn clone(&self) -> ValueConversionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValueConversionError

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

Formats the value using the given formatter.

impl Display for ValueConversionError

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

Formats the value using the given formatter.

impl Error for ValueConversionError

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.

impl From<ValueConversionError> for Error

fn from(source: ValueConversionError) -> Self

Converts to this type from the input type.

impl PartialEq for ValueConversionError

fn eq(&self, other: &ValueConversionError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
