Struct Scope 

pub struct Scope<'src> {
    pub namespace: Option<&'src str>,
    pub class_name: Option<&'src str>,
    pub function_name: Option<&'src str>,
}

Lexical scope context passed to each ScopeVisitor method.

Represents the immediately enclosing namespace, class-like definition, and named function or method at the point a node is visited. All fields are None when the node is at the global top level.

Namespace is set when inside a braced or simple namespace declaration. class_name is set inside class, interface, trait, and enum declarations; it is None for anonymous classes. function_name is set inside named functions and methods; it is None inside closures and arrow functions.

Fields

namespace: Option<&'src str>

Current namespace, or None for the global namespace.

This is a borrowed slice of the original source string, so copying or cloning the scope is always allocation-free.

class_name: Option<&'src str>

Name of the immediately enclosing class-like declaration, or None.

function_name: Option<&'src str>

Name of the immediately enclosing named function or method, or None.

Trait Implementations

impl<'src> Clone for Scope<'src>

fn clone(&self) -> Scope<'src>

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

Performs copy-assignment from source.

impl<'src> Debug for Scope<'src>

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

Formats the value using the given formatter.

impl<'src> Default for Scope<'src>

fn default() -> Scope<'src>

Returns the “default value” for a type.
