Struct rustc_ap_rustc_span::def_id::DefId

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

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

Fields

krate: CrateNum

index: DefIndex

Methods

impl DefId

pub fn local(index: DefIndex) -> DefId

Makes a local DefId from the given DefIndex.

pub fn is_local(self) -> bool

pub fn to_local(self) -> LocalDefId

pub fn is_top_level_module(self) -> bool

Trait Implementations

impl<CTX: HashStableContext> HashStable<CTX> for DefId

fn hash_stable(&self, hcx: &mut CTX, hasher: &mut StableHasher)

impl Ord for DefId

fn cmp(&self, other: &DefId) -> 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<DefId> for DefId

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

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

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

This method tests for !=.

impl PartialOrd<DefId> for DefId

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

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

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

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

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

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

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

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

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