Struct impl_tools_lib::SingletonScope

pub struct SingletonScope(_, _);

A Scope plus field values

This supports dereference to a Scope, allowing macro expansion via Scope::apply_attrs and other manipulation.

Tokens may be generated by Self::expand.

Implementations

impl SingletonScope

pub fn expand(self) -> TokenStream

Generate the TokenStream

This is a convenience function. It is valid to, instead, (1) call Scope::expand_impl_self on self, then (2) use the ToTokens impl on Scope.

Methods from Deref<Target = Scope>

pub fn apply_attrs( &mut self, find_rule: impl Fn(&Path) -> Option<&'static dyn ScopeAttr> )

Apply attribute rules

The supplied rules are applied in the order of definition, and their attributes removed from the item.

pub fn expand_impl_self(&mut self)

Expand impl Self

This is done automatically by Self::expand. It may be called earlier by a ScopeAttr if required. Calling multiple times is harmless.

Trait Implementations

impl Debug for SingletonScope

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for SingletonScope

type Target = Scope

The resulting type after dereferencing.

fn deref(&self) -> &Scope

Dereferences the value.

impl DerefMut for SingletonScope

fn deref_mut(&mut self) -> &mut Scope

Mutably dereferences the value.

impl ToTokens for SingletonScope

fn to_tokens(&self, tokens: &mut TokenStream)

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStreamwhere Self: Sized,

Convert self directly into a TokenStream object.
