Enum rand::seq::index::IndexVec

[−] Show declaration

pub enum IndexVec {
    // some variants omitted
}

[−] Expand description

A vector of indices.

Multiple internal representations are possible.

Implementations

impl IndexVec[−]

pub fn len(&self) -> usize[−]

Returns the number of indices

pub fn is_empty(&self) -> bool[−]

Returns true if the length is 0.

pub fn index(&self, index: usize) -> usize[−]

Return the value at the given index.

(Note: we cannot implement std::ops::Index because of lifetime restrictions.)

pub fn into_vec(self) -> Vec<usize>[−]

Return result as a Vec<usize>. Conversion may or may not be trivial.

pub fn iter(&self) -> IndexVecIter<'_>[−]

Iterate over the indices as a sequence of usize values

Trait Implementations

impl Clone for IndexVec[+]

[+] Show hidden undocumented items

fn clone(&self) -> IndexVec[−]

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)[−]

Performs copy-assignment from source.

impl Debug for IndexVec[+]

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

Formats the value using the given formatter.

impl From<Vec<u32, Global>> for IndexVec[+]

[+] Show hidden undocumented items

fn from(v: Vec<u32>) -> Self[−]

Performs the conversion.

impl From<Vec<usize, Global>> for IndexVec[+]

[+] Show hidden undocumented items

fn from(v: Vec<usize>) -> Self[−]

Performs the conversion.

impl IntoIterator for IndexVec[+]

type Item = usize

The type of the elements being iterated over.

type IntoIter = IndexVecIntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> IndexVecIntoIter[−]

fn eq(&self, other: &IndexVec) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.
