[−][src]Struct syntax::ext::hygiene::Mark
A mark is a unique ID associated with a macro expansion.
Methods
impl Mark
[src]
pub fn fresh(parent: Mark, expn_info: Option<ExpnInfo>) -> Mark
[src]
pub fn root() -> Mark
[src]
The mark of the theoretical expansion that generates freshly parsed, unexpanded AST.
pub fn as_u32(self) -> u32
[src]
pub fn from_u32(raw: u32) -> Mark
[src]
pub fn parent(self) -> Mark
[src]
pub fn expn_info(self) -> Option<ExpnInfo>
[src]
pub fn set_expn_info(self, info: ExpnInfo)
[src]
pub fn is_descendant_of(self, ancestor: Mark) -> bool
[src]
pub fn outer_is_descendant_of(self, ctxt: SyntaxContext) -> bool
[src]
mark.outer_is_descendant_of(ctxt)
is equivalent to but faster than
mark.is_descendant_of(ctxt.outer())
.
