Struct rustc_hir::def_id::DefIndex

pub struct DefIndex {
    private: u32,
}

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.

Fields

private: u32

Implementations

impl DefIndex

pub const MAX_AS_U32: u32

pub const MAX: DefIndex

pub fn from_usize(value: usize) -> DefIndex

pub fn from_u32(value: u32) -> DefIndex

pub unsafe fn from_u32_unchecked(value: u32) -> DefIndex

pub fn index(self) -> usize

Extracts the value of this index as an integer.

pub fn as_u32(self) -> u32

type Output = DefIndex

The resulting type after applying the + operator.

fn add(self, other: usize) -> DefIndex

Performs the + operation.

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.

impl Copy for DefIndex

impl Debug for DefIndex

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

impl Eq for DefIndex

impl From<u32> for DefIndex

fn from(value: u32) -> DefIndex

Performs the conversion.

fn from(value: usize) -> DefIndex

Performs the conversion.

impl Hash for DefIndex

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

Feeds this value into the given [Hasher].

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

impl Ord for DefIndex

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

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<DefIndex> for DefIndex

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

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

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

This method tests for !=.

impl PartialOrd<DefIndex> for DefIndex

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

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

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

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

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

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

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