Function definition

Fields

visibility: Visibility

name: Ident

generics: GenericParams

params: Vec<Param>

return_type: Option<Type>

where_clause: WhereClause

body: Option<Block>

Body is None for extern function declarations

is_extern: bool

Whether this is an extern function

is_async: bool

Whether this is an async function (async fn)

is_const: bool

Whether this is a const function (const fn)

attributes: Vec<Attribute>

Attributes attached to this function (e.g., #[energy_budget(...)])

energy_budget: Option<EnergyBudget>

Parsed energy budget constraint from #[energy_budget(...)] attribute

proc_macro_kind: Option<ProcMacroKind>

Procedural macro kind (if this function is a proc macro)

span: Span

Trait Implementations

impl Clone for Function

fn clone(&self) -> Function

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Function

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

Formats the value using the given formatter.

impl PartialEq for Function

fn eq(&self, other: &Function) -> 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.
