Reports when certain comment structures are present.
Note that this rule differs from ESLint's no-restricted-syntax
rule in expecting values within a single options object's
contexts property, and with the property context being used in place of
selector (as well as allowing for comment). The format also differs from
the format expected by eslint-plugin-query.
Unlike those rules, this is specific to finding comments attached to
structures, (whether or not you add a specific comment condition).
Note that if your parser supports comment AST (as jsdoc-eslint-parser is designed to do), you can just use ESLint's rule.
Set this to an array of strings representing the AST context (or an object with
context and comment properties) where you wish the rule to be applied.
Use the message property to indicate the specific error to be shown when an
error is reported for that context being found.
Set to "any" if you want the rule to apply to any jsdoc block throughout
your files (as is necessary for finding function blocks not attached to a
function declaration or expression, i.e., @callback or @function (or its
aliases @func or @method) (including those associated with an @interface).
See the "AST and Selectors" section of our README for more on the expected format.
