Extensions for TokenTree.

This trait is implemented for TokenTree in proc_macro and proc_macro2 if the corresponding feature is enabled.

Required Methods

fn kind(&self) -> TokenTreeKind

Get the kind of this TokenTree.

fn group(&self) -> Option<&Self::Group>

If this TokenTree is a TokenTree::Group, return a reference to the Group.

fn group_mut(&mut self) -> Option<&mut Self::Group>

If this TokenTree is a TokenTree::Group, return a mutable reference to the Group.

fn into_group(self) -> Option<Self::Group>

If this TokenTree is a TokenTree::Group, return the Group.

fn ident(&self) -> Option<&Self::Ident>

If this TokenTree is a TokenTree::Ident, return a reference to the Ident.

fn ident_mut(&mut self) -> Option<&mut Self::Ident>

If this TokenTree is a TokenTree::Ident, return a mutable reference to the Ident.

fn into_ident(self) -> Option<Self::Ident>

If this TokenTree is a TokenTree::Ident, return the Ident.

fn punct(&self) -> Option<&Self::Punct>

If this TokenTree is a TokenTree::Punct, return a reference to the Punct.

fn punct_mut(&mut self) -> Option<&mut Self::Punct>

If this TokenTree is a TokenTree::Punct, return a mutable reference to the Punct.

fn into_punct(self) -> Option<Self::Punct>

Check if this TokenTree is a TokenTree::Punct.

fn literal(&self) -> Option<&Self::Literal>

If this TokenTree is a TokenTree::Literal, return a reference to the Literal.

fn literal_mut(&mut self) -> Option<&mut Self::Literal>

If this TokenTree is a TokenTree::Literal, return a mutable reference to the Literal.

fn into_literal(self) -> Option<Self::Literal>

Check if this TokenTree is a TokenTree::Literal.

Provided Methods

fn is_group(&self) -> bool

Check if this TokenTree is a TokenTree::Group.

fn is_ident(&self) -> bool

Check if this TokenTree is a TokenTree::Ident.

fn is_punct(&self) -> bool

Check if this TokenTree is a TokenTree::Punct.

fn is_literal(&self) -> bool

Check if this TokenTree is a TokenTree::Literal.

fn flatten_group(&mut self)

If the TokenTree is a group with delimiter None containing a single item, replace the group with that item, recursively.
