Interface CodeActionProvider<T>

The code action interface defines the contract between extensions and the light bulb feature.

A code action can be any command that is known to the system.

interface CodeActionProvider<T extends CodeAction = CodeAction> {
    provideCodeActions(
        document: TextDocument,
        range: Range | Selection,
        context: CodeActionContext,
        token: CancellationToken,
    ): ProviderResult<(Command | T)[]>;
    resolveCodeAction?(
        codeAction: T,
        token: CancellationToken,
    ): ProviderResult<T>;
}

- context: CodeActionContext
  Context carrying additional information.

`Optional`resolveCodeAction

resolveCodeAction?(codeAction: T, token: CancellationToken): ProviderResult<T>
Given a code action fill in its edit-property. Changes to all other properties, like title, are ignored. A code action that has an edit will not be resolved.

Note that a code action provider that returns commands, not code actions, cannot successfully implement this function. Returning commands is deprecated and instead code actions should be returned.
Parameters
- codeAction: T
  A code action.
- token: CancellationToken
  A cancellation token.
Returns ProviderResult<T>
The resolved code action or a thenable that resolves to such. It is OK to return the given item. When no result is returned, the given item will be used.
