Enum InvalidDirectionError

pub enum InvalidDirectionError {
    Zero,
    Infinite,
    NaN,
}

An error indicating that a direction is invalid.

Variants

Zero

The length of the direction vector is zero or very close to zero.

Infinite

The length of the direction vector is std::f32::INFINITY.

NaN

The length of the direction vector is NaN.

Implementations

impl InvalidDirectionError

pub fn from_length(length: f32) -> Self

Creates an InvalidDirectionError from the length of an invalid direction vector.

Trait Implementations

impl Debug for InvalidDirectionError

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

Formats the value using the given formatter.

impl Display for InvalidDirectionError

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

Formats the value using the given formatter.

impl Error for InvalidDirectionError

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 InvalidDirectionError

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