Enum Cause 

pub enum Cause {
    Static(&'static str),
    Owned(String),
}

A short, cheap explanation attached to an OgeomError.

Static in the common case so that returning an error costs no allocation on paths that are hit often: failed intersections inside a boolean, for instance, are routine control flow rather than exceptional.

Variants

Static(&'static str)

A compile-time message.

Owned(String)

A message built at runtime.

Trait Implementations

impl Clone for Cause

fn clone(&self) -> Cause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cause

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

Formats the value using the given formatter.

impl Display for Cause

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

Formats the value using the given formatter.

impl Eq for Cause

impl From<&'static str> for Cause

fn from(s: &'static str) -> Self

Converts to this type from the input type.

impl From<Arguments<'_>> for Cause

fn from(a: Arguments<'_>) -> Self

Converts to this type from the input type.

impl From<String> for Cause

fn from(s: String) -> Self

Converts to this type from the input type.

impl PartialEq for Cause

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