Struct DefId 

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

A lightweight handle to a named definition.

Assigned during dependency analysis. Used as a key for looking up definition-level metadata (types, recursion status) in TypeContext.

Implementations

impl DefId

pub fn from_raw(index: u32) -> Self

pub fn as_u32(self) -> u32

pub fn index(self) -> usize

Trait Implementations

impl Clone for DefId

fn clone(&self) -> DefId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefId

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

Formats the value using the given formatter.

impl Hash for DefId

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 DefId

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