Create an IndexVec with n elements, where the value of each element is the result of func(i). (The underlying vector will be allocated only once, with a capacity of at least n.)

pub fn push(&mut self, d: T) -> I

pub fn pop(&mut self) -> Option<T>

pub fn len(&self) -> usize

pub fn next_index(&self) -> I

Gives the next index that will be assigned when push is called.

pub fn get_mut(&mut self, index: I) -> Option<&mut T>

pub fn pick2_mut(&mut self, a: I, b: I) -> (&mut T, &mut T)

Returns mutable references to two distinct elements, a and b.

Panics if a == b.

pub fn pick3_mut(&mut self, a: I, b: I, c: I) -> (&mut T, &mut T, &mut T)

Returns mutable references to three distinct elements.

Panics if the elements are not distinct.

pub fn convert_index_type<Ix: Idx>(self) -> IndexVec<Ix, T>

pub fn ensure_contains_elem(&mut self, elem: I, fill_value: impl FnMut() -> T)

Grows the index vector so that it contains an entry for elem; if that is already true, then has no effect. Otherwise, inserts new values as needed by invoking fill_value.

pub fn resize_to_elem(&mut self, elem: I, fill_value: impl FnMut() -> T)

impl<I: Idx, T> IndexVec<I, Option<T>>

IndexVec is often used as a map, so it provides some map-like APIs.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
