Enum ValueConversionError 

pub enum ValueConversionError {
    InvalidType {
        want: String,
        got: String,
        msg: String,
    },
    InvalidStructMember(Identifier),
    OutOfRange,
    BadState,
}

Indicates that the Value conversion has failed

Variants

InvalidType

A conversion was attempted to a type that is not compatible with this Value

Fields

want: String

Expected type name

got: String

Received type name

msg: String

Extra information

InvalidStructMember(Identifier)

A struct conversion found a field mismatch between types

OutOfRange

The target type does not have sufficient range to represent this Value

BadState

Some internal state is corrupt

Implementations

impl ValueConversionError

pub fn invalid_type( want: impl Into<String>, got: impl Into<String>, msg: impl Into<String>, ) -> Self

Constructs an InvalidType error

Trait Implementations

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.
