Project-wide search for a symbol matching the given query string.
The query-parameter should be interpreted in a relaxed way as the editor will apply its own highlighting
and scoring on the results. A good rule of thumb is to match case-insensitive and to simply check that the
characters of query appear in their order in a candidate symbol. Don't use prefix, substring, or similar
strict matching.
To improve performance implementors can implement resolveWorkspaceSymbol and then provide symbols with partial
location-objects, without a range defined. The editor will then call
resolveWorkspaceSymbol for selected symbols only, e.g. when opening a workspace symbol.
A query string, can be the empty string in which case all symbols should be returned.
A cancellation token.
An array of document highlights or a thenable that resolves to such. The lack of a result can be
signaled by returning undefined, null, or an empty array.
Given a symbol fill in its location. This method is called whenever a symbol
is selected in the UI. Providers can implement this method and return incomplete symbols from
provideWorkspaceSymbols which often helps to improve
performance.
The symbol that is to be resolved. Guaranteed to be an instance of an object returned from an
earlier call to provideWorkspaceSymbols.
A cancellation token.
The resolved symbol or a thenable that resolves to that. When no result is returned,
the given symbol is used.
The workspace symbol provider interface defines the contract between extensions and the symbol search-feature.
