pub fn span(&self) -> Span

pub fn kind(&self) -> ItemKind

pub fn requires_monomorphization(&self) -> bool

pub fn ty(&self) -> Ty

pub fn is_foreign_item(&self) -> bool

pub fn emit_mir<W: Write>(&self, w: &mut W) -> Result<()>

Trait Implementations

impl Clone for CrateItem

fn clone(&self) -> CrateItem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CrateDef for CrateItem

fn def_id(&self) -> DefId

Retrieve the unique identifier for the current definition.

fn name(&self) -> Symbol

Return the fully qualified name of the current definition.

fn trimmed_name(&self) -> Symbol

Return a trimmed name of this definition.

fn krate(&self) -> Crate

Return information about the crate where this definition is declared.

fn span(&self) -> Span

Return the span of this definition.

fn attrs_by_path(&self, attr: &[Symbol]) -> Vec<Attribute>

Return attributes with the given attribute name.

fn all_attrs(&self) -> Vec<Attribute>

Return all attributes of this definition.

impl CrateDefType for CrateItem

fn ty(&self) -> Ty

Returns the type of this crate item.

fn ty_with_args(&self, args: &GenericArgs) -> Ty

Retrieve the type of this definition by instantiating and normalizing it with args.

impl Debug for CrateItem

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

Formats the value using the given formatter.

impl From<StaticDef> for CrateItem

fn from(value: StaticDef) -> Self

Converts to this type from the input type.

impl Hash for CrateItem

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 PartialEq for CrateItem

fn eq(&self, other: &CrateItem) -> 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 Serialize for CrateItem

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<CrateItem> for Instance

Try to convert a crate item into an instance. The item cannot be generic in order to be converted into an instance.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(item: CrateItem) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<CrateItem> for StaticDef

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: CrateItem) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Instance> for CrateItem

Try to convert an instance into a crate item. Only user defined instances can be converted.

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Instance) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for CrateItem

impl Eq for CrateItem

impl StructuralPartialEq for CrateItem

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
