Struct rune::Id [−][src]
An opaque identifier that is associated with AST items.
The default implementation for an identifier is empty, meaning it does not
hold any value, and attempting to perform lookups over it will fail with an
error indicating that it’s empty with the string Id(*).
Implementations
impl Id[src]
pub fn initial() -> Id[src]
Construct the initial (non-empty) id.
pub fn new(index: usize) -> Option<Id>[src]
Construct a new opaque identifier.
pub fn next(self) -> Option<Id>[src]
Get the next id.
