Struct TypeHierarchyProvider 

pub struct TypeHierarchyProvider;

Provider for type hierarchy (inheritance) information

Implementations

impl TypeHierarchyProvider

pub fn new() -> TypeHierarchyProvider

Creates a new type hierarchy provider

pub fn prepare( &self, ast: &Node, code: &str, offset: usize, ) -> Option<Vec<TypeHierarchyItem>>

Prepare type hierarchy at position

pub fn find_supertypes( &self, ast: &Node, item: &TypeHierarchyItem, ) -> Vec<TypeHierarchyItem>

Find supertypes (parent classes and composed roles)

pub fn c3_mro(&self, ast: &Node, package: &str) -> Vec<String>

Compute the C3 Method Resolution Order (MRO) for a package.

Returns a linearized list starting with package itself, followed by ancestors in the order Perl’s C3 MRO would search them. Each class appears exactly once. If the C3 merge is inconsistent the algorithm falls back to a depth-first left-to-right order with deduplication.

pub fn find_subtypes( &self, ast: &Node, item: &TypeHierarchyItem, ) -> Vec<TypeHierarchyItem>

Find subtypes (child classes) that inherit from this class

Trait Implementations

impl Default for TypeHierarchyProvider

fn default() -> TypeHierarchyProvider

Returns the “default value” for a type.
