Enum ParseQError 

pub enum ParseQError {
    Malformed,
    IntOverflow,
    ZeroDenominator,
    OutOfBudget,
}

Why a string could not be parsed as a Q.

Variants

Malformed

The input matched no special spelling and was not of the form int or int/int.

IntOverflow

A numeral did not fit an i64.

ZeroDenominator

The denominator was zero. "1/0" in input is a malformed numeral, not a computation, so it is rejected rather than read as PosInf.

OutOfBudget

The pair does not reduce to a value inside the width budget.

Trait Implementations

impl Clone for ParseQError

fn clone(&self) -> ParseQError

Returns a duplicate of the value.

impl Copy for ParseQError

impl Debug for ParseQError

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

Formats the value using the given formatter.

impl Eq for ParseQError

impl Error for ParseQError

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 Hash for ParseQError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ParseQError

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

Equality operator ==.

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

Inequality operator !=.
