Struct rslint_core::groups::errors::NoInnerDeclarations

pub struct NoInnerDeclarations {
    pub disallowed: Vec<String>,
}

Disallow variable and function declarations in nested blocks.

Prior to ECMAScript 6, function declarations were only allowed in the first level of a program or the body of another function, although parsers sometimes incorrectly accept it. This rule only applies to function declarations, not function expressions.

Invalid Code Examples

function foo() {
    if (bar) {
        // Move this to foo's body, outside the if statement
        function bar() {}
    }
}

if (bar) {
    var foo = 5;
}

Correct Code Examples

function foo() {}

var bar = 5;

Fields

disallowed: Vec<String>

What declarations to disallow in nested blocks, it can include two possible options: "functions" and "variables", you can include either or, or both. Disallows only functions by default.

Implementations

impl NoInnerDeclarations

pub fn new() -> Self

impl NoInnerDeclarations

pub fn disallow_all() -> Self

Trait Implementations

impl Clone for NoInnerDeclarations

fn clone(&self) -> NoInnerDeclarations

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl CstRule for NoInnerDeclarations

fn check_node(&self, node: &SyntaxNode, ctx: &mut RuleCtx) -> Option<()>

Check an individual node in the syntax tree. You can use the match_ast macro to make matching a node to an ast node easier. The reason this uses nodes and not a visitor is because nodes are more flexible, converting them to an AST node has zero cost and you can easily traverse surrounding nodes. Defaults to doing nothing.

fn check_token(&self, token: &SyntaxToken, ctx: &mut RuleCtx) -> Option<()>

Check an individual token in the syntax tree. Defaults to doing nothing.

fn check_root(&self, root: &SyntaxNode, ctx: &mut RuleCtx) -> Option<()>

Check the root of the tree one time. This method is guaranteed to only be called once. The root's kind will be either SCRIPT or MODULE. Defaults to doing nothing.

impl Debug for NoInnerDeclarations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NoInnerDeclarations

fn default() -> Self

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for NoInnerDeclarations where
    NoInnerDeclarations: Default, 

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Rule for NoInnerDeclarations

fn name(&self) -> &'static str

A unique, kebab-case name for the rule.

fn group(&self) -> &'static str

The name of the group this rule belongs to.

impl Serialize for NoInnerDeclarations

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
