Struct Idx 

pub struct Idx<T> {
    pub raw: u32,
    /* private fields */
}

A typed index into an arena.

The phantom type prevents mixing indices from different arenas.

Fields

raw: u32

Trait Implementations

impl<T> Clone for Idx<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T> Copy for Idx<T>

impl<T: Debug> Debug for Idx<T>

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

Formats the value using the given formatter.

impl<T> Eq for Idx<T>

impl<T> PartialEq for Idx<T>

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