Enum NativeError 

pub enum NativeError {
    FunctionNotFound(String),
    WrongParameterCount(usize),
    WrongParameterType,
    IndexOutOfBounds(usize),
    IndexNegative,
    CustomError(String),
}

Error types created by super::NativeFunction calls. NativeError::CustomError can be used for general purpose errors.

Variants

FunctionNotFound(String)

Trait Implementations

impl Debug for NativeError

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

Formats the value using the given formatter.

impl Display for NativeError

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

Formats the value using the given formatter.

impl Error for NativeError

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<&str> for NativeError

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for NativeError

fn from(value: String) -> Self

Converts to this type from the input type.

impl PartialEq for NativeError

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