Implementations

impl Scope

pub fn new(node: &SyntaxNode<NixLanguage>) -> Option<Self>

Construct a new Scope if this is an AST node that opens a new scope

pub fn is_lambda_arg(&self) -> bool

Is this a ...: ... which can be ignored in Settings

pub fn is_lambda_pattern_name(&self, name: &Ident) -> bool

Is this a { ... }: ... which can be ignored in Settings

pub fn bindings(&self) -> Box<dyn Iterator<Item = Binding>>

The set of Bindings this Scope introduces

pub fn bodies(&self) -> Box<dyn Iterator<Item = SyntaxNode<NixLanguage>>>

The code subtrees in which the introduced variables are available

pub fn inherits_from(&self, name: &Ident) -> bool

Check the inherit (var) ... and inherit vars clauses for a given name.

Although a scope may shadow existing variable bindings, it can inherit bindings from the outer scope.

pub fn color(&self) -> Color

Output color for dead code warnings
