Enum ItemId

pub(crate) enum ItemId {
    DefId(DefId),
    Auto {
        trait_: DefId,
        for_: DefId,
    },
    Blanket {
        impl_id: DefId,
        for_: DefId,
    },
}

Variants

DefId(DefId)

A “normal” item that uses a DefId for identification.

Auto

Identifier that is used for auto traits.

Fields

trait_: DefId

for_: DefId

Blanket

Identifier that is used for blanket implementations.

Fields

impl_id: DefId

for_: DefId

Implementations

Trait Implementations

impl Clone for ItemId

fn clone(&self) -> ItemId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ItemId

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

Formats the value using the given formatter.

impl From<DefId> for ItemId

fn from(id: DefId) -> Self

Converts to this type from the input type.

impl Hash for ItemId

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 ItemId

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

impl Copy for ItemId

impl Eq for ItemId

impl StructuralPartialEq for ItemId

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.
