Struct ContList 

pub struct ContList(pub Vec<Cont>);

A continuation list, head first.

Tuple Fields

0: Vec<Cont>

Implementations

impl ContList

pub fn name_dummies(&mut self)

Gives every attribute continuation a random dummy name, so two trampolines in one module never collide.

pub fn invoke(&self, body: TokenStream) -> TokenStream

Invokes the head with @announce_format "1" [self] body, where body is ENTRY* REST (a derive or attribute head gets the same tokens in the dummy enum).

pub fn invoke_with_options( &self, options: Option<&TokenStream>, body: TokenStream, ) -> TokenStream

Like invoke, with a global options group @announce_format "1" (options) [..] ... A derive or attribute head is refused (compile_error!) when the group starts with expr (is_expression_position).
