Enum CircleTangency 

pub enum CircleTangency {
    External,
    Internal {
        sign: f64,
    },
}

Tangency between two circles.

Variants

External

Circles touch from outside: |c₂ − c₁| = r₁ + r₂.

Internal

One circle inside the other: |c₂ − c₁| = sign·(r₁ − r₂); sign keeps which circle is the outer one.

Fields

sign: f64

+1 when circle 1 is the outer circle, −1 otherwise.

Trait Implementations

impl Clone for CircleTangency

fn clone(&self) -> CircleTangency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CircleTangency

impl Debug for CircleTangency

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CircleTangency

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CircleTangency

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
