Required Methods

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

Returns reference of inner attrs if not verbatim; otherwise Err

fn attrs_mut(&mut self) -> Result<&mut Vec<Attribute>>

Returns mutable reference of inner attrs if not verbatim; otherwise Err

fn function_or_method(&self) -> Result<&dyn FunctionLike>

Returns function-like trait object of Item::Fn, ImplItem::Method, or TraitItem::Method

fn constant(&self) -> Result<&dyn ConstLike>

Returns const-like trait object of Item::Const, ImplItem::Const, or TraitItem::Const

fn is_type(&self) -> bool

Returns true if self matches *ItemType

fn is_macro(&self) -> bool

Returns true if self matches *ItemMacro

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
