Trait Implementations

impl Clone for EvalError

fn clone(&self) -> EvalError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Error for EvalError

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 EvalError

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<EvalError> for Value

fn from(e: EvalError) -> Self

Converts to this type from the input type.

impl From<String> for EvalError

fn from(s: String) -> Self

Converts to this type from the input type.

impl<'a> TryFrom<&'a Value> for &'a EvalError

type Error = ValueError

The type returned in the event of a conversion error.

fn try_from(v: &'a Value) -> Result<Self, Self::Error>

Performs the conversion.
