Struct rslint_core::groups::errors::NoDupeKeys

pub struct NoDupeKeys {}

Disallow duplicate keys in object literals.

Object literals allow keys to be declared multiple times, however this causes unwanted behavior by shadowing the first declaration.

Invalid Code Examples

let foo = {
    bar: 1,
    baz: 2,
    bar: 3
}

Implementations

impl NoDupeKeys

pub fn new() -> Self

Trait Implementations

impl Clone for NoDupeKeys

fn clone(&self) -> NoDupeKeys

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CstRule for NoDupeKeys

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 NoDupeKeys

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

Formats the value using the given formatter.

impl Default for NoDupeKeys

fn default() -> NoDupeKeys

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for NoDupeKeys

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

Deserialize this value from the given Serde deserializer.

impl Rule for NoDupeKeys

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 NoDupeKeys

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

Serialize this value into the given Serde serializer.
