Struct pomelo_hir::arena::Arena

pub struct Arena<T> {
    inner: Vec<T>,
}

Basically a Vec.

Fields

inner: Vec<T>

Implementations

impl<T> Arena<T>

pub fn new() -> Self

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

pub fn capacity(&self) -> usize

pub fn alloc(&mut self, val: T) -> Idx<T>

pub fn items(&self) -> impl Iterator + '_

pub fn items_mut(&mut self) -> impl Iterator + '_

pub fn get(&self, idx: Idx<T>) -> &T

This does not return an Option because we assume the index is valid. This should be alright, because we don’t provide a way to construct an Idx on its own.

pub fn get_mut(&mut self, idx: Idx<T>) -> &mut T

Trait Implementations

impl<T: Clone> Clone for Arena<T>

fn clone(&self) -> Arena<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Arena<T>

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

Formats the value using the given formatter.

impl<T> Default for Arena<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: PartialEq> PartialEq<Arena<T>> for Arena<T>

fn eq(&self, other: &Arena<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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