Struct syntex_syntax::ast::SyntaxContext

pub struct SyntaxContext(pub u32);

A SyntaxContext represents a chain of macro-expandings and renamings. Each macro expansion corresponds to a fresh u32. This u32 is a reference to a table stored in thread-local storage. The special value EMPTY_CTXT is used to indicate an empty syntax context.
