Struct stable_mir::crate_def::DefId

pub struct DefId(pub(crate) usize);

A unique identification number for each item accessible for the current compilation unit.

Tuple Fields

0: usize

Trait Implementations

impl Clone for DefId

fn clone(&self) -> DefId

Returns a copy 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 IndexedVal for DefId

fn to_val(index: usize) -> Self

fn to_index(&self) -> usize

impl PartialEq for DefId

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

impl Copy for DefId

impl Eq for DefId

impl StructuralPartialEq for DefId

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
