pub struct Symbol(SymbolIndex);Expand description
An interned string.
Internally, a Symbol is implemented as an index, and all operations
(including hashing, equality, and ordering) operate on that index. The use
of rustc_index::newtype_index! means that Option<Symbol> only takes up 4 bytes,
because rustc_index::newtype_index! reserves the last 256 values for tagging purposes.
Note that Symbol cannot directly be a rustc_index::newtype_index! because it
implements fmt::Debug, Encodable, and Decodable in special ways.
