Struct TransItemSource

pub struct TransItemSource {
    pub item: RustcItem,
    pub kind: TransItemSourceKind,
}

The id of an untranslated item. Note that a given DefId may show up as multiple different item sources, e.g. a constant will have both a Global version (for the constant itself) and a FunDecl one (for its initializer function).

Fields

item: RustcItem

kind: TransItemSourceKind

Implementations

impl TransItemSource

pub fn new(item: RustcItem, kind: TransItemSourceKind) -> Self

pub fn from_item( item: &ItemRef, kind: TransItemSourceKind, monomorphize: bool, ) -> Self

Refers to the given item. Depending on monomorphize, this chooses between the monomorphic and polymorphic versions of the item.

pub fn polymorphic(def_id: &DefId, kind: TransItemSourceKind) -> Self

Refers to the polymorphic version of this item.

pub fn monomorphic(item: &ItemRef, kind: TransItemSourceKind) -> Self

Refers to the monomorphic version of this item.

pub fn def_id(&self) -> &DefId

pub(crate) fn with_kind(&self, kind: TransItemSourceKind) -> Self

Keep the same def_id but change the kind.

pub(crate) fn parent(&self) -> Option<Self>

For virtual items that have a parent (typically a method impl), return this parent. Does not attempt to generally compute the parent of an item. Used to compute names.

pub(crate) fn is_derived_item(&self) -> bool

Whether this item is the “main” item for this def_id or not (e.g. drop impl/methods are not the main item).

fn sort_key(&self) -> impl Ord + '_

Value with which we order values.

Trait Implementations

impl Clone for TransItemSource

fn clone(&self) -> TransItemSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransItemSource

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

Formats the value using the given formatter.

impl Hash for TransItemSource

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TransItemSource

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TransItemSource

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TransItemSource

Manual impls because DefId is not orderable.

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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