Detailed Description

template<class Type>
class clang::clangd::Key< Type >

Values in a Context are indexed by typed keys.

Key<T> serves two purposes:

• it provides a lookup key for the context (each Key is unique),
• it makes lookup type-safe: a Key<T> can only map to a T (or nothing).

Example: Key<int> RequestID; Key<int> Version;

Context Ctx = Context::empty().derive(RequestID, 10).derive(Version, 3); assert(*Ctx.get(RequestID) == 10); assert(*Ctx.get(Version) == 3);

Keys are typically used across multiple functions, so most of the time you would want to make them static class members or global variables.
