Struct rustc_typeck::hir::def_id::DefId

pub struct DefId {
    pub krate: CrateNum,
    pub index: DefIndex,
}

🔬 This is a nightly-only experimental API. (rustc_private)

A DefId identifies a particular definition, by combining a crate index and a def index.

Trait Implementations

impl Decodable for DefId

fn decode<__D>(__arg_0: &mut __D) -> Result<DefId, __D::Error> where __D: Decoder

🔬 This is a nightly-only experimental API. (rustc_private)

impl PartialOrd<DefId> for DefId

fn partial_cmp(&self, __arg_0: &DefId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &DefId) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &DefId) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &DefId) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &DefId) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl PartialEq<DefId> for DefId

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

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

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

This method tests for !=.

impl Hash for DefId

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

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 DepGraphSafe for DefId

A DefId on its own doesn't give access to any particular state. You must fetch the state from the various maps or generate on-demand queries, all of which create reads.

impl Clone for DefId

fn clone(&self) -> DefId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Eq for DefId

impl Debug for DefId

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

Formats the value using the given formatter.

impl Encodable for DefId

fn encode<__S>(&self, __arg_0: &mut __S) -> Result<(), __S::Error> where __S: Encoder

🔬 This is a nightly-only experimental API. (rustc_private)

impl Copy for DefId

impl Ord for DefId

fn cmp(&self, __arg_0: &DefId) -> Ordering

This method returns an Ordering between self and other.
