◆ BackgroundIndex()

clang::clangd::BackgroundIndex::BackgroundIndex ( const ThreadsafeFS & TFS,
const GlobalCompilationDatabase & CDB,
BackgroundIndexStorage::Factory IndexStorageFactory,
Options Opts )

Creates a new background index and starts its threads.

The current Context will be propagated to each worker thread.
