Struct enum_vec::EnumVec

pub struct EnumVec<T: EnumLike> { /* fields omitted */ }

A vector which efficiently stores enum variants.

Methods

impl<T: EnumLike> EnumVec<T>

pub fn new() -> Self

pub fn with_capacity(n: usize) -> Self

pub fn capacity(&self) -> usize

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

pub fn set(&mut self, i: usize, x: T)

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

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

pub fn reserve(&mut self, additional: usize)

pub fn shrink_to_fit(&mut self)

pub fn truncate(&mut self, len: usize)

pub fn swap_remove(&mut self, index: usize) -> T

pub fn insert(&mut self, index: usize, element: T)

Insert and remove need a better implementation

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

pub fn append(&mut self, other: &mut Self)

pub fn clear(&mut self)

pub fn len(&self) -> usize

pub unsafe fn set_len(&mut self, len: usize)

pub fn is_empty(&self) -> bool

pub fn split_off(&mut self, at: usize) -> Self

pub fn resize(&mut self, new_len: usize, value: T) where     T: Clone,

pub unsafe fn get_raw_unchecked(&self, i: usize) -> usize

Get the raw discriminant without bounds checking

pub unsafe fn set_raw_unchecked(&mut self, i: usize, discr: usize)

Set the raw discriminant without bounds checking. It is assumed that the discriminant has only Self::BITS_PER_ELEM bits set.
