Detailed Description

template<typename Container>
class clang::clangd::Memoize< Container >

Memoize is a cache to store and reuse computation results based on a key.

Memoize<DenseMap<int, bool>> PrimeCache; for (int I : RepetitiveNumbers) if (PrimeCache.get(I, [&] { return expensiveIsPrime(I); })) llvm::errs() << "Prime: " << I << "\n";

The computation will only be run once for each key. This class is threadsafe. Concurrent calls for the same key may run the computation multiple times, but each call will return the same result.
