[−][src]Struct syntax::source_map::hygiene::Mark
A mark is a unique ID associated with a macro expansion.
Methods
impl Mark
[src]
pub fn fresh(parent: Mark) -> 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 set_default_transparency(self, transparency: Transparency)
[src]
pub fn is_descendant_of(self, ancestor: Mark) -> bool
[src]
pub fn least_ancestor(a: Mark, b: Mark) -> Mark
[src]
Computes a mark such that both input marks are descendants of (or equal to) the returned mark. That is, the following holds:
let la = least_ancestor(a, b); assert!(a.is_descendant_of(la)) assert!(b.is_descendant_of(la))
