Struct IdVec

pub struct IdVec<K, V> { /* private fields */ }

Vec wrapper that uses typed indexes.

Implementations

impl<K, V> IdVec<K, V>

pub fn with_capacity(cap: usize) -> Self

Create a new IdVec with the given capacity.

pub fn len(&self) -> usize

Get the current length

pub fn is_empty(&self) -> bool

True if len == 0

pub fn iter(&self) -> impl Iterator<Item = &V>

Iterate through immutable references to values

pub fn iter_mut(&mut self) -> impl Iterator<Item = &mut V>

Iterate through mutable references to values

impl<K, V: Clone> IdVec<K, V>

pub fn fill(val: V, len: usize) -> Self

Create a new IdVec, filled with len copies of val.

impl<K: Into<usize>, V> IdVec<K, V>

pub fn get_unchecked(&self, k: K) -> &V

Get the value with id k.

pub fn get(&self, k: K) -> Option<&V>

pub fn get_mut_unchecked(&mut self, k: K) -> &mut V

Get a mutable reference to value with id k.

pub fn get_mut(&mut self, k: K) -> Option<&mut V>

impl<K: From<usize>, V> IdVec<K, V>

pub fn push(&mut self, v: V) -> K

Push v into the underlying vec, and return an id that can be used to retrieve it later.

impl<K: Into<usize>, V: Default + Clone> IdVec<K, V>

pub fn insert(&mut self, k: K, v: V)

Insert value v at position k. The underlying vec will be extended if k is beyond its current capacity, and new entries will be filled with a default value.

Trait Implementations

impl<K: Clone, V: Clone> Clone for IdVec<K, V>

fn clone(&self) -> IdVec<K, V>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<K: Debug, V: Debug> Debug for IdVec<K, V>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K: Default, V: Default> Default for IdVec<K, V>

fn default() -> IdVec<K, V>

Returns the “default value” for a type.

impl<K: Hash, V: Hash> Hash for IdVec<K, V>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<K: PartialEq, V: PartialEq> PartialEq for IdVec<K, V>

fn eq(&self, other: &IdVec<K, V>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
