Enum rand::seq::index::IndexVec

source · [−]

pub enum IndexVec {
    // some variants omitted
}

Expand description

A vector of indices.

Multiple internal representations are possible.

Implementations

source

impl IndexVec

source

pub fn len(&self) -> usize

Returns the number of indices

source

pub fn is_empty(&self) -> bool

Returns true if the length is 0.

source

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.)

source

pub fn into_vec(self) -> Vec<usize>

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

source

pub fn iter(&self) -> IndexVecIter<'_>ⓘNotable traits for IndexVecIter<'a>`impl<'a> Iterator for IndexVecIter<'a> type Item = usize;`

Iterate over the indices as a sequence of usize values
