Struct rslint_core::groups::errors::NoNewSymbol

pub struct NoNewSymbol {}

Disallow constructing Symbol using new.

Symbol shouldn't be constructed using new keyword since it results in a TypeError, instead it should be called as a function.

Incorrect code examples

// This call results in TypeError
const fooSymbol = new Symbol("foo");

Correct code examples

const fooSymbol = Symbol("foo");

Implementations

impl NoNewSymbol

pub fn new() -> Self

Trait Implementations

impl Clone for NoNewSymbol

fn clone(&self) -> NoNewSymbol

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CstRule for NoNewSymbol

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 NoNewSymbol

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

Formats the value using the given formatter.

impl Default for NoNewSymbol

fn default() -> NoNewSymbol

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for NoNewSymbol

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

Deserialize this value from the given Serde deserializer.

impl Rule for NoNewSymbol

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.

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

Optional docs for the rule, an empty string by default

impl Serialize for NoNewSymbol

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

Serialize this value into the given Serde serializer.
