Struct Address 

pub struct Address(/* private fields */);

Memory address of an AST node in arena.

Implementations

impl Address

pub const DUMMY: Self

Dummy address.

Never equal to any real Address, but is equal to itself.

pub fn from_ptr<T>(p: *const T) -> Self

Get the memory address of a pointer to an AST node in arena.

The pointer must point to an AST node in the arena (not on the stack), or the returned Address will be meaningless.

If the AST node is in a Box, the address is guaranteed to be a unique identifier for the duration of the arena’s existence. If the node is in a Vec, then the Address may not remain accurate if the Vec is resized or has elements added or removed before this node.

Trait Implementations

impl Clone for Address

fn clone(&self) -> Address

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Address

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

Formats the value using the given formatter.

impl GetAddress for Address

fn address(&self) -> Address

Address of an Address is itself.

impl Hash for Address

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 PartialEq for Address

fn eq(&self, other: &Address) -> 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.
