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

pub enum IndexVec {
    // some variants omitted
}

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, Global>

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

pub fn into_iter(self) -> IndexVecIntoIter

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

Trait Implementations

impl Clone for IndexVec

pub 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

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

Formats the value using the given formatter.

impl From<Vec<u32, Global>> for IndexVec

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

Performs the conversion.

impl From<Vec<usize, Global>> for IndexVec

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

Performs the conversion.

impl PartialEq<IndexVec> for IndexVec

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

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

#[must_use]

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

This method tests for !=.
