[−][src]Struct swc_common::Mark
A mark is a unique id associated with a macro expansion.
Methods
impl Mark
[src]
pub fn fresh(parent: Mark) -> Self
[src]
pub fn root() -> Self
[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 is_builtin(self) -> bool
[src]
pub fn set_is_builtin(self, is_builtin: bool)
[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:
ⓘThis example is not tested
let la = least_ancestor(a, b); assert!(a.is_descendant_of(la)) assert!(b.is_descendant_of(la))
