Trait AttributeExtension

pub trait AttributeExtension {
    // Required method
    fn get_self(&self) -> &Attribute;

    // Provided methods
    fn parse_comma_args<T: Parse>(&self) -> Result<Vec<T>> { ... }
    fn unfeatured(&self) -> Option<Attribute> { ... }
}

Required Methods

fn get_self(&self) -> &Attribute

Provided Methods

fn parse_comma_args<T: Parse>(&self) -> Result<Vec<T>>

Parse all arguments as comma-separated types.

fn unfeatured(&self) -> Option<Attribute>

Unwrap the feature flag from the attribute. E.g. #[cfg_attr(feature = "some_feature", derive(Debug))] becomes the syn::Meta defined as derive(Debug).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
