Struct rslint_core::groups::errors::NoEmpty

pub struct NoEmpty {
    pub disallow_empty_functions: bool,
    pub allow_empty_catch: bool,
}

Disallow empty block statements.

Block statements with nothing in them are very common when refactoring, however they can get confusing really quickly. This rule reports empty block statements and empty switch case blocks if they do not have a comment.

Invalid Code Examples

{}

if (foo) {

}

Correct Code Examples

if (foo) {
    /* todo */
}

Fields

disallow_empty_functions: bool

Whether to disallow empty block statements in function declarations, arrow functions, getters, setters, and methods.

allow_empty_catch: bool

Whether to allow empty catch clauses without a comment.

Implementations

impl NoEmpty

pub fn new() -> Self

Trait Implementations

impl Clone for NoEmpty

fn clone(&self) -> NoEmpty

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CstRule for NoEmpty

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 NoEmpty

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

Formats the value using the given formatter.

impl Default for NoEmpty

fn default() -> NoEmpty

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for NoEmpty where
    NoEmpty: 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 NoEmpty

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 NoEmpty

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

Serialize this value into the given Serde serializer.
