Enum FunctionError 

pub enum FunctionError {
    ArgError(ArgError),
    ArgCountMismatch {
        expected: ArgCount,
        received: usize,
    },
    NoOverload {
        expected: HashSet<ArgumentSignature>,
        received: ArgumentSignature,
    },
}

Available on crate feature functions only.

An error that occurs when calling a DynamicFunction or DynamicFunctionMut.

Variants

ArgError(ArgError)

An error occurred while converting an argument.

ArgCountMismatch

The number of arguments provided does not match the expected number.

Fields

expected: ArgCount

Expected argument count. ArgCount for overloaded functions will contain multiple possible counts.

received: usize

Number of arguments received.

NoOverload

No overload was found for the given set of arguments.

Fields

expected: HashSet<ArgumentSignature>

The set of available argument signatures.

received: ArgumentSignature

The received argument signature.

Trait Implementations

impl Debug for FunctionError

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

Formats the value using the given formatter.

impl Display for FunctionError

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

Formats the value using the given formatter.

impl Error for FunctionError

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<ArgError> for FunctionError

fn from(source: ArgError) -> Self

Converts to this type from the input type.

impl PartialEq for FunctionError

fn eq(&self, other: &FunctionError) -> 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.
