Struct rustc_hir::definitions::DefKey

pub struct DefKey {
    pub parent: Option<DefIndex>,
    pub disambiguated_data: DisambiguatedDefPathData,
}

A unique identifier that we can use to lookup a definition precisely. It combines the index of the definition’s parent (if any) with a DisambiguatedDefPathData.

Fields

parent: Option<DefIndex>

The parent path.

disambiguated_data: DisambiguatedDefPathData

The identifier of this node.

Implementations

impl DefKey

pub(crate) fn compute_stable_hash(&self, parent: DefPathHash) -> DefPathHash

Trait Implementations

impl Clone for DefKey

fn clone(&self) -> DefKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DefKey

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for DefKey

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl<__E: Encoder> Encodable<__E> for DefKey

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

impl PartialEq<DefKey> for DefKey

fn eq(&self, other: &DefKey) -> bool

This method tests for self and other values to be equal, and is used by ==.

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
