Struct persist_o_vec::Persist

pub struct Persist<T> { /* fields omitted */ }

Iteration will not always be in order

Methods

impl<T> Persist<T>

pub fn with_capacity(capacity: usize) -> Persist<T>

Allocate with capacity. This is the only way to create a new persistent vec.

Panics

Will panic if the selected capacity is larger than the ability for Persist to internally index in to

pub fn len(&self) -> usize

Returns the actual used length regardless of capacity

pub fn clear(&mut self)

pub fn get(&self, index: usize) -> Option<&T>

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

pub fn is_index_live(&self, index: usize) -> bool

pub fn push(&mut self, value: T)

Push T on to the Persistent Vec

Panics

Will panic if trying to push over capacity

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

pub fn remove(&mut self, index: usize) -> Option<T>

Remove the item at this index and return it if it exists. Does not shift elements after it to the left.
