Enum FromValuesError

pub enum FromValuesError {
    ValueConversion(ValueConvertError),
    ExpectedValue {
        stream_name: String,
    },
    InvalidHashMap {
        stream_name: String,
        expected_num_params: usize,
        got_number_params: usize,
    },
    StreamKindMismatch,
}

Represents the errors that can occur when constructing an arbitraty type from a vector of StreamValues.

Variants

ValueConversion(ValueConvertError)

The StreamValue can not be converted to desired Rust type.

ExpectedValue

A Non-Optional value was expected but None was given as a StreamValue.

Fields

stream_name: String

The name of the stream for which a value was expected.

InvalidHashMap

The stream instance hashmap can not be converted to the desired Rust HashMap.

Fields

stream_name: String

The name of the stream for which the parameters did not match.

expected_num_params: usize

The number of parameters expected by the implementation.

got_number_params: usize

The number of parameters as defined in the specification.

StreamKindMismatch

A parameterized stream was expected but a non-parametrized value was received, or vice versa.

Trait Implementations

impl Debug for FromValuesError

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

Formats the value using the given formatter.

impl Display for FromValuesError

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

Formats the value using the given formatter.

impl Error for FromValuesError

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<FromValuesError> for StructVerdictError

fn from(value: FromValuesError) -> Self

Converts to this type from the input type.

impl From<ValueConvertError> for FromValuesError

fn from(value: ValueConvertError) -> Self

Converts to this type from the input type.
