Trait Implementations

impl<S: BinaryOp> BinaryOp for Dual<S>

fn op(self, b: Self) -> Self

二項演算

fn op_assign_r(&mut self, b: Self)

where Self: Clone,

二項演算$\circ$で(右側から)代入操作($a \leftarrow a \circ b$)をする。

fn op_assign_l(&mut self, b: Self)

where Self: Clone,

二項演算$\circ$で(左側から)代入操作($a \leftarrow b \circ a$)をする。

impl<S: Clone> Clone for Dual<S>

fn clone(&self) -> Dual<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for Dual<S>

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

Formats the value using the given formatter.

impl<S: Default> Default for Dual<S>

fn default() -> Dual<S>

Returns the “default value” for a type.

impl<S: Identity> Identity for Dual<S>

fn id() -> Self

単位元

impl<S: Inverse> Inverse for Dual<S>

fn inv(self) -> Self

逆元

impl<S: PartialEq> PartialEq for Dual<S>

fn eq(&self, other: &Dual<S>) -> 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.
