Implementations

impl<A> MutableList<A>

pub fn make() -> Self

Empty list.

pub fn append(&self, value: A)

Push value at the back.

pub fn prepend(&self, value: A)

Push value at the front.

pub fn head(&self) -> Option<A>

where A: Clone,

First element, if any.

pub fn tail(&self) -> Chunk<A>

where A: Clone,

All elements after the first (empty when length ≤ 1).

pub fn last(&self) -> Option<A>

where A: Clone,

Last element, if any.

pub fn pop(&self) -> Option<A>

Remove and return the last element.

pub fn shift(&self) -> Option<A>

Remove and return the first element.

pub fn to_chunk(&self) -> Chunk<A>

where A: Clone,

Snapshot of the whole list as an immutable Chunk.

pub fn length(&self) -> usize

Number of elements.

pub fn for_each(&self, f: impl FnMut(&A))

Invokes f for each element in order (holds the mutex for the whole walk).
