Struct rustc::hir::def_id::DefIndex

pub struct DefIndex(_);

Unstable (rustc_private)

A DefIndex is an index into the hir-map for a crate, identifying a particular definition. It should really be considered an interned shorthand for a particular DefPath.

Methods

impl DefIndex

fn new(x: usize) -> DefIndex

fn from_u32(x: u32) -> DefIndex

fn as_usize(&self) -> usize

fn as_u32(&self) -> u32

Trait Implementations

Derived Implementations

impl Copy for DefIndex

impl Hash for DefIndex

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 Decodable for DefIndex

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

impl Encodable for DefIndex

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

impl PartialEq for DefIndex

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

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

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

This method tests for !=.

impl PartialOrd for DefIndex

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

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

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

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

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

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

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

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

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

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

impl Ord for DefIndex

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

This method returns an Ordering between self and other.

impl Eq for DefIndex

impl Debug for DefIndex

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

Formats the value using the given formatter.

impl Clone for DefIndex

fn clone(&self) -> DefIndex

Returns a copy of the value.

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

Performs copy-assignment from source.
