Enum IntFromSExprError

#[non_exhaustive]
pub enum IntFromSExprError {
    NotAnAtom,
    ParseIntError(ParseIntError),
}

An error which can be returned when trying to interpret an s-expr as an integer.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotAnAtom

The s-expr is a list, not an atom, and therefore cannot be converted to an integer.

ParseIntError(ParseIntError)

There was an error parsing the atom as an integer.

Trait Implementations

impl Debug for IntFromSExprError

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

Formats the value using the given formatter.

impl Display for IntFromSExprError

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

Formats the value using the given formatter.

impl Error for IntFromSExprError

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<ParseIntError> for IntFromSExprError

fn from(e: ParseIntError) -> Self

Converts to this type from the input type.
