Enum FloatError 

pub enum FloatError {
    NaN,
    PosInf,
    NegInf,
    OutOfRange,
    NoneOperand,
}

Errors that can occur when creating or operating on finite floats

Variants

NaN

Value is NaN (Not a Number)

PosInf

Value is positive infinity

NegInf

Value is negative infinity

OutOfRange

Value is outside the valid range for this type

NoneOperand

Right-hand side operand is None in Option arithmetic

Trait Implementations

impl Clone for FloatError

fn clone(&self) -> FloatError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FloatError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FloatError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FloatError

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

Formats the value using the given formatter.

impl Error for FloatError

Available on crate feature std only.

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<FloatError> for ParseFloatError

fn from(err: FloatError) -> Self

Converts to this type from the input type.

impl PartialEq for FloatError

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

impl Serialize for FloatError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for FloatError

impl Eq for FloatError

impl StructuralPartialEq for FloatError
