Extension methods for syn::Item.

Provides variant predicates (is_struct, is_enum, is_fn, etc.), conversions (as_struct, as_enum, as_fn, etc.), and common field accessors (attrs, ident, generics, vis) that work across all applicable variants.

Examples

use zyn::ext::ItemExt;

assert!(item.is_struct());
let attrs = item.attrs();
let ident = item.ident().unwrap();

Required Methods

fn is_struct(&self) -> bool

Returns true if this is Item::Struct.

fn is_fn(&self) -> bool

Returns true if this is Item::Fn.

fn is_trait(&self) -> bool

Returns true if this is Item::Trait.

fn is_impl(&self) -> bool

Returns true if this is Item::Impl.

fn is_mod(&self) -> bool

fn as_struct(&self) -> Option<&ItemStruct>

Returns the inner syn::ItemStruct if this is a struct.

fn as_enum(&self) -> Option<&ItemEnum>

Returns the inner syn::ItemEnum if this is an enum.

fn as_union(&self) -> Option<&ItemUnion>

Returns the inner syn::ItemUnion if this is a union.

fn as_fn(&self) -> Option<&ItemFn>

Returns the inner syn::ItemFn if this is a function.

fn as_trait(&self) -> Option<&ItemTrait>

Returns the inner syn::ItemTrait if this is a trait.

fn as_impl(&self) -> Option<&ItemImpl>

Returns the inner syn::ItemImpl if this is an impl block.

fn as_mod(&self) -> Option<&ItemMod>

Returns the inner syn::ItemMod if this is a module.

fn as_type(&self) -> Option<&ItemType>

fn attrs(&self) -> &[Attribute]

Returns the attributes for this item. All variants have attributes.

fn ident(&self) -> Option<&Ident>

Returns the identifier if this variant has one. Returns None for Impl, Use, ForeignMod, and Verbatim.

fn generics(&self) -> Option<&Generics>
