Implementations

impl StaticDef

pub fn ty(&self) -> Ty

Return the type of this static definition.

pub fn eval_initializer(&self) -> Result<Allocation, Error>

Evaluate a static’s initializer, returning the allocation of the initializer’s memory.

Trait Implementations

impl Clone for StaticDef

fn clone(&self) -> StaticDef

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CrateDef for StaticDef

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 Debug for StaticDef

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 From<StaticDef> for Instance

fn from(value: StaticDef) -> Self

Converts to this type from the input type.

impl From<StaticDef> for MonoItem

fn from(value: StaticDef) -> Self

Converts to this type from the input type.

impl Hash for StaticDef

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 StaticDef

fn eq(&self, other: &StaticDef) -> 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 StaticDef

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 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 StaticDef

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 StaticDef

impl Eq for StaticDef

impl StructuralPartialEq for StaticDef

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.
