Implementations

impl Permutation

pub fn get(&self, i: usize) -> usize

i番目の要素を返す。

$b_i = a_{P_i}$を満たすbを返す。

pub fn is_identity(&self) -> bool

単位元であるとき、trueを返す。

pub fn compose(self, other: Self) -> Self

操作を合成する。

pub fn inv(self) -> Self

逆操作を返す。

Trait Implementations

impl BinaryOp for Permutation

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 Clone for Permutation

fn clone(&self) -> Permutation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Permutation

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

Formats the value using the given formatter.

impl Default for Permutation

fn default() -> Permutation

Returns the “default value” for a type.

impl Identity for Permutation

fn id() -> Self

単位元

impl Inverse for Permutation

fn inv(self) -> Self

逆元

impl PartialEq for Permutation

fn eq(&self, other: &Self) -> 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 TryFrom<Vec<usize>> for Permutation

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: Vec<usize>) -> Result<Self, Self::Error>

Performs the conversion.

impl Associative for Permutation

impl Set for Permutation
