Trait anim::Cursor

pub trait Cursor {
    type Item;
    fn size(&self) -> Option<usize>;
    fn index(&self, n: usize) -> Self::Item;
}

like Iterator, but does not consume any element

built-in types that derives Cursor

• Vec<T>
• [T]
• &[T]
• Box<T> where T:Cursor
• &T where T:Cursor

Associated Types

type Item

item of the cursor

Required methods

fn size(&self) -> Option<usize>

none means that it’s infinite

fn index(&self, n: usize) -> Self::Item

seek to specified element
