Implementations

impl AstFragmentKind

pub fn name(self) -> &'static str

pub(in expand) fn make_from<'a>(
    self,
    result: Box<dyn MacResult + 'a>
) -> Option<AstFragment>

impl AstFragmentKind

pub(crate) fn dummy(self, span: Span) -> AstFragment

pub fn supports_macro_expansion(self) -> bool

Fragment supports macro expansion and not just inert attributes, cfg and cfg_attr.

    self,
    items: I
) -> AstFragment
