Trait GroupExt 

pub trait GroupExt {
    // Required method
    fn map<F>(&self, f: F) -> Self
       where F: FnOnce(TokenStream) -> TokenStream;

    // Provided methods
    fn map_tts<F>(&self, f: F) -> Self
       where F: FnMut(TokenTree) -> TokenTree,
             Self: Sized { ... }
    fn flat_map_tts<F, I>(&self, f: F) -> Self
       where F: FnMut(TokenTree) -> I,
             I: IntoIterator<Item = TokenTree>,
             Self: Sized { ... }
}

Required Methods

fn map<F>(&self, f: F) -> Self

where F: FnOnce(TokenStream) -> TokenStream,

Provided Methods

fn map_tts<F>(&self, f: F) -> Self

where F: FnMut(TokenTree) -> TokenTree, Self: Sized,

fn flat_map_tts<F, I>(&self, f: F) -> Self

where F: FnMut(TokenTree) -> I, I: IntoIterator<Item = TokenTree>, Self: Sized,

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.
