Enum SyntheticItem 

pub enum SyntheticItem {
    Array,
    Slice,
    Tuple(usize),
}

We create some extra DefIds to represent things that rustc doesn’t have a DefId for. This makes the pipeline much easier to have “real” def_ids for them. We generate fake struct-like items for each of: arrays, slices, and tuples. This makes it easier to emit trait impls for these types, especially with monomorphization. This enum tracks identifies these builtin types.

Variants

Array

Fake ADT representing the [T; N] type.

Slice

Fake ADT representing the [T] type.

Tuple(usize)

Fake ADT representing the length-n tuple (A, B, ...).

Trait Implementations

impl Clone for SyntheticItem

fn clone(&self) -> SyntheticItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyntheticItem

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

Formats the value using the given formatter.

impl Hash for SyntheticItem

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 SyntheticItem

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