Struct rustc_span::def_id::LocalDefId

pub struct LocalDefId {
    pub local_def_index: DefIndex,
}

A LocalDefId is equivalent to a DefId with krate == LOCAL_CRATE. Since we encode this information in the type, we can ensure at compile time that no DefIds from upstream crates get thrown into the mix. There are quite a few cases where we know that only DefIds from the local crate are expected; a DefId from a different crate would signify a bug somewhere. This is when LocalDefId comes in handy.

Implementations

impl LocalDefId

pub fn to_def_id(self) -> DefId

pub fn is_top_level_module(self) -> bool

Trait Implementations

impl Clone for LocalDefId

fn clone(&self) -> LocalDefId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LocalDefId

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

Formats the value using the given formatter.

impl<D: SpanDecoder> Decodable<D> for LocalDefId

fn decode(d: &mut D) -> LocalDefId

impl<E: SpanEncoder> Encodable<E> for LocalDefId

fn encode(&self, s: &mut E)

impl From<LocalDefId> for DefId

fn from(local: LocalDefId) -> DefId

Converts to this type from the input type.

impl From<LocalModDefId> for LocalDefId

fn from(typed: LocalModDefId) -> Self

Converts to this type from the input type.

impl Hash for LocalDefId

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<CTX: HashStableContext> HashStable<CTX> for LocalDefId

fn hash_stable(&self, hcx: &mut CTX, hasher: &mut StableHasher)

impl Idx for LocalDefId

fn new(idx: usize) -> Self

fn index(self) -> usize

fn increment_by(&mut self, amount: usize)

fn plus(self, amount: usize) -> Self

impl PartialEq for LocalDefId

fn eq(&self, other: &LocalDefId) -> 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<CTX: HashStableContext> ToStableHashKey<CTX> for LocalDefId

type KeyType = DefPathHash

fn to_stable_hash_key(&self, hcx: &CTX) -> DefPathHash

impl Copy for LocalDefId

impl Eq for LocalDefId

impl !Ord for LocalDefId

impl !PartialOrd for LocalDefId

impl StructuralPartialEq for LocalDefId

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.
