A function definition.

Fields

attrs: Vec<PureAttribute>

Attributes.

vis: PureVis

Visibility.

is_async: bool

Is async (explicit async fn)?

is_async_inferred: bool

Is async inferred from return type (Pin<Box<dyn Future<...>>>)? This is typically set when #[async_trait] or similar macros are used.

is_const: bool

Is const?

is_unsafe: bool

Is unsafe?

abi: Option<String>

ABI (e.g., "C", "Rust", "system"). None means default Rust ABI.

name: String

Function name.

generics: PureGenerics

Generic parameters.

params: Vec<PureParam>

Parameters.

ret: Option<PureType>

Return type (None = unit).

body: PureBlock

Function body.

Implementations

impl PureFn

pub fn is_effectively_async(&self) -> bool

Returns true if the function is async (either explicit or inferred).

This includes:

• Explicit async fn declarations
• Functions with Pin<Box<dyn Future<...>>> return type (e.g., from #[async_trait])

Trait Implementations

impl Clone for PureFn

fn clone(&self) -> PureFn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PureFn

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

Formats the value using the given formatter.

impl PartialEq for PureFn

fn eq(&self, other: &PureFn) -> 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 ToSyn for PureFn

type Output = ItemFn

syn output type produced from self.

fn to_syn(&self) -> Result<ItemFn, ToSynError>

Convert self back into its syn representation.

impl Eq for PureFn

impl StructuralPartialEq for PureFn
