Struct rustc::hir::map::definitions::DefKey

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

Unstable (rustc_private)

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>

Unstable (rustc_private)

Parent path.

disambiguated_data: DisambiguatedDefPathData

Unstable (rustc_private)

Identifier of this node.

impl Hash for DefKey

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl Eq for DefKey

impl PartialEq for DefKey

fn eq(&self, __arg_0: &DefKey) -> bool

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

fn ne(&self, __arg_0: &DefKey) -> bool

This method tests for !=.

impl Debug for DefKey

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

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.
