Struct TypeId 

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

A dense, per-runtime-instance index into the type registry (resolved decision, impl plan §1). Ids are not stable across runs; anything persistent identifies types by name (filename is identity, design §4.3).

Implementations

impl TypeId

pub fn index(self) -> u32

pub fn from_index(index: u32) -> Self

Rebuild an id from its index — the C ABI’s spelling of a TypeId. A forged index is caught by Registry::get, never UB.

Trait Implementations

impl Clone for TypeId

fn clone(&self) -> TypeId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeId

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

Formats the value using the given formatter.

impl Hash for TypeId

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 TypeId

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