Struct rslint_core::groups::errors::NoExtraSemi

pub struct NoExtraSemi {}

Disallow unneeded semicolons.

Unneeded semicolons are often caused by typing mistakes, while this is not an error, it can cause confusion when reading the code. This rule disallows empty statements (extra semicolons).

Invalid Code Examples

if (foo) {
    ;
}

class Foo {
    constructor() {};
}

impl NoExtraSemi

pub fn new() -> Self

Trait Implementations

impl Clone for NoExtraSemi

fn clone(&self) -> NoExtraSemi

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CstRule for NoExtraSemi

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 NoExtraSemi

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

Formats the value using the given formatter.

impl Default for NoExtraSemi

fn default() -> NoExtraSemi

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for NoExtraSemi

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

Deserialize this value from the given Serde deserializer.

impl Rule for NoExtraSemi

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 NoExtraSemi

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

Serialize this value into the given Serde serializer.
