Detailed Description

Collect declarations (symbols) from an AST.

It collects most declarations except:

• Implicit declarations
• Anonymous declarations (anonymous enum/class/struct, etc)
• Declarations in anonymous namespaces in headers
• Local declarations (in function bodies, blocks, etc)
• Template specializations
• Library-specific private declarations (e.g. private declaration generated by protobuf compiler)

References to main-file symbols are not collected.

See also shouldCollectSymbol(...).

Clients (e.g. clangd) can use SymbolCollector together with index::indexTopLevelDecls to retrieve all symbols when the source file is changed.

Returns true if we are interested in references and declarations from FID.

If this function return false, bodies of functions inside those files will be skipped to decrease indexing time.
