Enum nannou::rand::seq::index::IndexVec

pub enum IndexVec {
    // some variants omitted
}

A vector of indices.

Multiple internal representations are possible.

Methods

impl IndexVec

pub fn len(&self) -> usize

Returns the number of indices

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.

Important traits for IndexVecIter<'a>

impl<'a> Iterator for IndexVecIter<'a> type Item = usize;

pub fn iter(&'a self) -> IndexVecIter<'a>

Iterate over the indices as a sequence of usize values

Important traits for IndexVecIntoIter

impl Iterator for IndexVecIntoIter type Item = usize;

pub fn into_iter(self) -> IndexVecIntoIter

Convert into an iterator over the indices as a sequence of usize values

Trait Implementations

impl From<Vec<u32>> for IndexVec

fn from(v: Vec<u32>) -> IndexVec

Performs the conversion.

impl From<Vec<usize>> for IndexVec

fn from(v: Vec<usize>) -> IndexVec

Performs the conversion.

impl Debug for IndexVec

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

Formats the value using the given formatter.

impl PartialEq<IndexVec> for IndexVec

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

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

#[must_use]

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Clone for IndexVec

fn clone(&self) -> IndexVec

Returns a copy of the value.

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

Performs copy-assignment from source.
