Enum Item 

pub enum Item {
    Fn(FnDecl),
    Struct(StructDecl),
    Enum(EnumDecl),
    Interface(InterfaceDecl),
}

a top-level declaration: a function, a struct, an enum, or an interface. fn Type.method definitions are an Item::Fn whose FnDecl carries an optional type_name.

Variants

Fn(FnDecl)

a fn declaration – a free function, or, if type_name is set, a fn Type.method method definition.

Struct(StructDecl)

a struct declaration with typed fields.

Enum(EnumDecl)

an enum declaration with data-carrying variants.

Interface(InterfaceDecl)

an interface declaration – a set of method signatures, no bodies.

Implementations

impl Item

pub fn span(&self) -> Span

the source span of this item, opening keyword to closing brace.

each item kind wraps a struct that carries the span; this delegates to it. exhaustive over every kind, so a new item kind forces an arm here.

Trait Implementations

impl Clone for Item

fn clone(&self) -> Item

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Item

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

Formats the value using the given formatter.

impl PartialEq for Item

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