Struct ArithError 

pub struct ArithError {
    pub message: String,
    pub span: Range<usize>,
}

An error from tokenizing, parsing, or evaluating $(( )). message is the full, final text shown to the caller; span is the byte range in the arithmetic source the error concerns, when one exists (evaluation errors over already-resolved values carry 0..0 — the message already names the values).

Fields

message: String

span: Range<usize>

Trait Implementations

impl Clone for ArithError

fn clone(&self) -> ArithError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArithError

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

Formats the value using the given formatter.

impl Display for ArithError

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

Formats the value using the given formatter.

impl Error for ArithError

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 PartialEq for ArithError

fn eq(&self, other: &ArithError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
